7
7 STEP 1 INSTALL OVM SERVER amp OVM MANAGER
71 CREATE A VIRTUALBOX VM BY IMPORTING THE VIRTUALBOX TEMPLATE FOR ORACLE VM SERVER
During this step the user is going to create a first Virtualbox VM using the Virtualbox template OracleVMServer311build365ova available on Oracle public web site This VM will be our OVM Server NOTE The normal way of installing Oracle VM Server is to boot on an ISO filecdrom For purposes of this lab and due to the time constraint we use the VirtualBox template to save time
a) In VirtualBox go to gtFilegtImport Appliance and select the file
OracleVMServer311build365ova
b) In ldquoAppliance settingsrdquo o Go to name and double-click on OracleVMServer311 Change name to
ldquoHOL9870_ovm-srvrdquo o Change CPU to 2 o Change RAM to 2048MB o Click on Import and Click on Agree to Accept License Agreement
c) Wait for the import to complete (about 2 minutes)
d) Go to Settings and Modify Network according to the following instructions o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in Attached o Expand the Advanced section o Select ldquoAllow Allrdquo for Promiscuous mode
Make sure to enable the promiscuous mode on the network interfaces If not your Oracle VM virtual machine will not be accessible from your host machine (laptop here)
o Repeat all actions for Adapter 2
O Click OK to exit Settings
8
72 START AND CONFIGURE THE ORACLE VM SERVER
a) In the VirtualBox admin console select the VM ldquoHOL9870_ovm-srvrdquo and Click Start
b) Look at the VM console and wait for message ldquoEnter Static IP addressrdquo
c) Enter the following information o For the static IP address enter ldquo192168562rdquo o For the netmask enter ldquo2552552550rdquo (default) o For the gateway enter ldquo192168561rdquo o For the DNS enter ldquo192168561rdquo o For the hostname enter ldquoovm-srvoowcomrdquo Notes DNS and gateway
o We donrsquot have DNS server and DNS domain in place (and donrsquot need to) but when using VirtualBox template for Oracle VM Server we need to enter an IP address for server (you can enter any IP address since it will be ignored)
o We donrsquot need an network gateway since we only used the VirtualBox internal network Yet VirtualBox template for Oracle VM Server will ask for an gateway IP address (you can enter any IP address since it will be ignored)
9
d) Your OVM Server is now ready and you should see the following on the console
Note the root password for this VM is ldquoovsrootrdquo
e) To gain access back to the mouse press the right ldquoCTRLrdquo key on your keyboard and minimize the ldquoovm-srvrdquo window
f) IMPORTANT On your physical machine native OS (Oracle Linux during the OpenWorld lab) In Application-gtSystem Tools-gtTerminal open a new terminal and ping 192168562 (ovm-srv) to check that the Virtualbox VM is OK
10
73 CREATE A VIRTUALBOX VM BY IMPORTING THE VIRTUALBOX TEMPLATE FOR ORACLE VM MANAGER
During this step the user is going to create a second Virtualbox VM For the creation of this VM will we use the pre-existing Virtualbox template OracleVMManager311build365ova This VM will be our OVM Manager The normal way of installing Oracle VM Manager is to install a Linux Server (Oracle Linux or Redhat Linux) and then to install Oracle VM Manager from a ISO cdrom Here we use the VirtualBox template to save time
a) In VirtualBox go to gtFilegtImport Appliance and select the file OracleVMManager311build365ova
b) In ldquoAppliance settingsrdquo go to name and double-click OracleVMManager311build365 and change name to ldquoHOL9870_ovm-mgrrdquo Click on ldquoImportrdquo and click on Agree to accept License Agreement Note no need to change the RAM (4096 MB) and CPU (1 vcpu)
c) Wait for the import to complete (about 3 minutes)
d) Select the VM ldquoHOL9870_ovm-mgrrdquo and Click on ldquoSettingsrdquo o Go to Network and select ldquoHost-Only Adapterrdquo in Attached for Adapter 1
Note no need to set promiscuous mode to ldquoAllow allrdquo for the network interface as no VM will run on the manager
74 START AND CONFIGURE THE ORACLE VM MANAGER VM
a) In the VirtualBox admin console select the VM ldquoHOL9870_ovm-mgrrdquo and Click Start
b) Look at the VM console and wait for message ldquoNew Unix Passwdrdquo
c) Enter the following o For ldquoNew Unix passwdrdquo enter ldquoovsrootrdquo twice (same as Oracle VM Server password)
Ignore warning ldquoBAD PASSWORDrdquo this is because password is not secure o For static IP address enter ldquo192168563rdquo o For netmask enter ldquo2552552550rdquo (default) o For gateway enter ldquo192168561rdquo o For DNS server enter ldquo192168561rdquo o For hostname enter ldquoovm-mgroowcomrdquo
d) Wait for the VM to be ready (when Gnome Desktop displayed) (about 2 minutes) e) To gain access back to the mouse stroke right ldquoCRTLrdquo key on your keyboard and Minimize
the ldquoHOL9870_ovm-mgrrdquo window f) On your Oracle Linux desktop open a new terminal ( gtApplicationsgtSystems
ToolsgtTerminal) and ping 192168563 (ovm-mgr) to check that the Virtualbox VM is OK g) Minimize the OracleVM Manager Window
11
8 STEP 2 INSTALL ZFS STORAGE APPLIANCE In this LAB we will run main OVM operation on a ZFS Storage Appliance (iSCSI access) using the ldquoStorage Connect plug-inrdquo feature of OVM This feature enables the storage to be provisioned directly from OVM admin console (OVM Manager) simplifying the global management Since we donrsquot have real ZFS Storage Appliance for the lab we will use the ZFS SA simulator which is a tool we can run in a VirtualBox VM
81 CREATE A VIRTUALBOX VM FOR THE ZFS SA SIMULATOR
a) On your physical machine unzip the file
~HOL_OOWLAB3_HOL9870SunStorageVBoxzip This will create a directory named vbox-2011100118
b) In VirtualBox go to gtFilegtImport Appliance and select the file Sun ZFS Storage 7000ovf stored in the directory vbox-2011100118
c) In ldquoAppliance settingsrdquo o Go to name and double-click on Sun_ZFS_Storage_7000 Change name to
ldquoHOL9870_zfssardquo o Go to Systems and Change CPU to 1 o Click on Import
d) Wait for the import to complete (about 2 minutes)
e) Modify Storage settings
o Select the VM HOL9870_zfssa and Click on ldquoSettingsrdquo
o Go to Storage select Sun ZFS Storage 7000-disk2vmdk and click on icon to remove this virtual disk
o Repeat those actions for disk3 to disk16
o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings
14
82 START AND CONFIGURE THE ZFS SA SIMULATOR VIRTUALBOX VM
a) In the VirtualBox admin console select the VM ldquoHOL9870_zfssardquo and Click Start

o You should now see a message ldquosuccessfully configuredrdquo
83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files
o readmetxt o OVMPLuginzip o ZFSSAWorkflowszip
c) Unzip the file OVMPluginzip
This will create 2 files
o OVMPluginAdminGuidepdf (documentation) o osc-oracle-s7k-012-45el5noarchrpm (RPM to install on the OVM Server)
d) Install the RPM file on the OVM server
From the physical machine open a new terminal $ scp osc-oracle-s7k-012-45el5noarchrpm root192168562tmp $ ssh root192168562
[rootovm-srv ~] rpm ndashivh tmposc-oracle-s7k-012-45el5noarchrpm
e) Fix a bug on the OVM Server (only present in OVM Server created from the OVA file build 365 o Modifiy the file initiatornameiscsi
rootovm-srv ] vi etciscsiinitiatornameiscsi
Add laquo InitiatorName= raquo in the front of the first line Ask your instructor if you are not familiar with vi
o The file should now look like InitiatorName=iqn1988-12comoracle66624642f860
o Restart the iscsid service and exit the terminal session [rootovm-srv ] service iscsid restart
[rootovm-srv ] exit
23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

At the beginning of this lab only the physical laptop is installed with Oracle Linux 6 update 3 + VirtualBox + Java JRE (blue rectangle) You will create the VirtualBox and OVM virtual machines during the lab using the steps described in this document At the end of this lab you will have a complete running testing platform for Oracle VM using ZFS SA iSCSI shared storage
7
7 STEP 1 INSTALL OVM SERVER amp OVM MANAGER
71 CREATE A VIRTUALBOX VM BY IMPORTING THE VIRTUALBOX TEMPLATE FOR ORACLE VM SERVER
During this step the user is going to create a first Virtualbox VM using the Virtualbox template OracleVMServer311build365ova available on Oracle public web site This VM will be our OVM Server NOTE The normal way of installing Oracle VM Server is to boot on an ISO filecdrom For purposes of this lab and due to the time constraint we use the VirtualBox template to save time
a) In VirtualBox go to gtFilegtImport Appliance and select the file
OracleVMServer311build365ova
b) In ldquoAppliance settingsrdquo o Go to name and double-click on OracleVMServer311 Change name to
ldquoHOL9870_ovm-srvrdquo o Change CPU to 2 o Change RAM to 2048MB o Click on Import and Click on Agree to Accept License Agreement
c) Wait for the import to complete (about 2 minutes)
d) Go to Settings and Modify Network according to the following instructions o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in Attached o Expand the Advanced section o Select ldquoAllow Allrdquo for Promiscuous mode
Make sure to enable the promiscuous mode on the network interfaces If not your Oracle VM virtual machine will not be accessible from your host machine (laptop here)
o Repeat all actions for Adapter 2
O Click OK to exit Settings
8
72 START AND CONFIGURE THE ORACLE VM SERVER
a) In the VirtualBox admin console select the VM ldquoHOL9870_ovm-srvrdquo and Click Start
b) Look at the VM console and wait for message ldquoEnter Static IP addressrdquo
c) Enter the following information o For the static IP address enter ldquo192168562rdquo o For the netmask enter ldquo2552552550rdquo (default) o For the gateway enter ldquo192168561rdquo o For the DNS enter ldquo192168561rdquo o For the hostname enter ldquoovm-srvoowcomrdquo Notes DNS and gateway
o We donrsquot have DNS server and DNS domain in place (and donrsquot need to) but when using VirtualBox template for Oracle VM Server we need to enter an IP address for server (you can enter any IP address since it will be ignored)
o We donrsquot need an network gateway since we only used the VirtualBox internal network Yet VirtualBox template for Oracle VM Server will ask for an gateway IP address (you can enter any IP address since it will be ignored)
9
d) Your OVM Server is now ready and you should see the following on the console
Note the root password for this VM is ldquoovsrootrdquo
e) To gain access back to the mouse press the right ldquoCTRLrdquo key on your keyboard and minimize the ldquoovm-srvrdquo window
f) IMPORTANT On your physical machine native OS (Oracle Linux during the OpenWorld lab) In Application-gtSystem Tools-gtTerminal open a new terminal and ping 192168562 (ovm-srv) to check that the Virtualbox VM is OK
10
73 CREATE A VIRTUALBOX VM BY IMPORTING THE VIRTUALBOX TEMPLATE FOR ORACLE VM MANAGER
During this step the user is going to create a second Virtualbox VM For the creation of this VM will we use the pre-existing Virtualbox template OracleVMManager311build365ova This VM will be our OVM Manager The normal way of installing Oracle VM Manager is to install a Linux Server (Oracle Linux or Redhat Linux) and then to install Oracle VM Manager from a ISO cdrom Here we use the VirtualBox template to save time
a) In VirtualBox go to gtFilegtImport Appliance and select the file OracleVMManager311build365ova
b) In ldquoAppliance settingsrdquo go to name and double-click OracleVMManager311build365 and change name to ldquoHOL9870_ovm-mgrrdquo Click on ldquoImportrdquo and click on Agree to accept License Agreement Note no need to change the RAM (4096 MB) and CPU (1 vcpu)
c) Wait for the import to complete (about 3 minutes)
d) Select the VM ldquoHOL9870_ovm-mgrrdquo and Click on ldquoSettingsrdquo o Go to Network and select ldquoHost-Only Adapterrdquo in Attached for Adapter 1
Note no need to set promiscuous mode to ldquoAllow allrdquo for the network interface as no VM will run on the manager
74 START AND CONFIGURE THE ORACLE VM MANAGER VM
a) In the VirtualBox admin console select the VM ldquoHOL9870_ovm-mgrrdquo and Click Start
b) Look at the VM console and wait for message ldquoNew Unix Passwdrdquo
c) Enter the following o For ldquoNew Unix passwdrdquo enter ldquoovsrootrdquo twice (same as Oracle VM Server password)
Ignore warning ldquoBAD PASSWORDrdquo this is because password is not secure o For static IP address enter ldquo192168563rdquo o For netmask enter ldquo2552552550rdquo (default) o For gateway enter ldquo192168561rdquo o For DNS server enter ldquo192168561rdquo o For hostname enter ldquoovm-mgroowcomrdquo
d) Wait for the VM to be ready (when Gnome Desktop displayed) (about 2 minutes) e) To gain access back to the mouse stroke right ldquoCRTLrdquo key on your keyboard and Minimize
the ldquoHOL9870_ovm-mgrrdquo window f) On your Oracle Linux desktop open a new terminal ( gtApplicationsgtSystems
ToolsgtTerminal) and ping 192168563 (ovm-mgr) to check that the Virtualbox VM is OK g) Minimize the OracleVM Manager Window
11
8 STEP 2 INSTALL ZFS STORAGE APPLIANCE In this LAB we will run main OVM operation on a ZFS Storage Appliance (iSCSI access) using the ldquoStorage Connect plug-inrdquo feature of OVM This feature enables the storage to be provisioned directly from OVM admin console (OVM Manager) simplifying the global management Since we donrsquot have real ZFS Storage Appliance for the lab we will use the ZFS SA simulator which is a tool we can run in a VirtualBox VM
81 CREATE A VIRTUALBOX VM FOR THE ZFS SA SIMULATOR
a) On your physical machine unzip the file
~HOL_OOWLAB3_HOL9870SunStorageVBoxzip This will create a directory named vbox-2011100118
b) In VirtualBox go to gtFilegtImport Appliance and select the file Sun ZFS Storage 7000ovf stored in the directory vbox-2011100118
c) In ldquoAppliance settingsrdquo o Go to name and double-click on Sun_ZFS_Storage_7000 Change name to
ldquoHOL9870_zfssardquo o Go to Systems and Change CPU to 1 o Click on Import
d) Wait for the import to complete (about 2 minutes)
e) Modify Storage settings
o Select the VM HOL9870_zfssa and Click on ldquoSettingsrdquo
o Go to Storage select Sun ZFS Storage 7000-disk2vmdk and click on icon to remove this virtual disk
o Repeat those actions for disk3 to disk16
o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings
14
82 START AND CONFIGURE THE ZFS SA SIMULATOR VIRTUALBOX VM
a) In the VirtualBox admin console select the VM ldquoHOL9870_zfssardquo and Click Start
b) Look at the VM console
and wait for message ldquoPress any key to begin configuring appliance []rdquo
c) Enter the following information (use the TAB key to go to next field) o Host Name zfssa o DNS Domain oowcom o IP Address 192168565 o IP Netmask 2552552550 o Default Router 192168561 o DNS Server 192168561 o Password ovsroot o Press ESC and 1 when finished
d) Wait for the VM to finish its boot (OK when you can see ldquozfssa console loginrdquo)
15
o To gain access back to the mouse press the right ldquoCTRLrdquo key on your keyboard and minimize the ldquoHOL9870_zfssardquo window
e) As explained on the console the next steps of the initial configuration will be done in
the ZFS SA admin console in a web browser o Open a web browser (Firefox during OpenWorld lab) and open the URL
https192168565215
o Ignore security warnings because of https self signed certificates In Firefox click on ldquoI understand the Risksrdquo ldquothen Add Exceptionsrdquo and ldquoConfirm Security Exceptionsrdquo
o Ignore the message ldquoUnsupported Browserrdquo and click Continue
o Login with Username root and Password ovsroot
o Click on Start to start the initial configuration of the ZFS SA simulator
16
o In Step 1 of 6 (Configure networking) click on Commit since no modification needed
o In Step 2 of 6 (Configure DNS) click on Commit since no modification is needed
17
o In Step 3 of 6 (Configure Time) click on Commit since no modification is needed
o In Step 4 of 6 (Configure Name Services) click on Commit since no modification is needed

19
o In step Registration amp Support click on later (no need to register the product here)
o Ignore the warning about not registering
o You should now see a message ldquosuccessfully configuredrdquo
83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files
o readmetxt o OVMPLuginzip o ZFSSAWorkflowszip
c) Unzip the file OVMPluginzip
This will create 2 files
o OVMPluginAdminGuidepdf (documentation) o osc-oracle-s7k-012-45el5noarchrpm (RPM to install on the OVM Server)
d) Install the RPM file on the OVM server
From the physical machine open a new terminal $ scp osc-oracle-s7k-012-45el5noarchrpm root192168562tmp $ ssh root192168562
[rootovm-srv ~] rpm ndashivh tmposc-oracle-s7k-012-45el5noarchrpm
e) Fix a bug on the OVM Server (only present in OVM Server created from the OVA file build 365 o Modifiy the file initiatornameiscsi
rootovm-srv ] vi etciscsiinitiatornameiscsi
Add laquo InitiatorName= raquo in the front of the first line Ask your instructor if you are not familiar with vi
o The file should now look like InitiatorName=iqn1988-12comoracle66624642f860
o Restart the iscsid service and exit the terminal session [rootovm-srv ] service iscsid restart
[rootovm-srv ] exit
23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance

Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on

c) Enter the following information o For the static IP address enter ldquo192168562rdquo o For the netmask enter ldquo2552552550rdquo (default) o For the gateway enter ldquo192168561rdquo o For the DNS enter ldquo192168561rdquo o For the hostname enter ldquoovm-srvoowcomrdquo Notes DNS and gateway
o We donrsquot have DNS server and DNS domain in place (and donrsquot need to) but when using VirtualBox template for Oracle VM Server we need to enter an IP address for server (you can enter any IP address since it will be ignored)
o We donrsquot need an network gateway since we only used the VirtualBox internal network Yet VirtualBox template for Oracle VM Server will ask for an gateway IP address (you can enter any IP address since it will be ignored)
9
d) Your OVM Server is now ready and you should see the following on the console
Note the root password for this VM is ldquoovsrootrdquo
e) To gain access back to the mouse press the right ldquoCTRLrdquo key on your keyboard and minimize the ldquoovm-srvrdquo window
f) IMPORTANT On your physical machine native OS (Oracle Linux during the OpenWorld lab) In Application-gtSystem Tools-gtTerminal open a new terminal and ping 192168562 (ovm-srv) to check that the Virtualbox VM is OK
10
73 CREATE A VIRTUALBOX VM BY IMPORTING THE VIRTUALBOX TEMPLATE FOR ORACLE VM MANAGER
During this step the user is going to create a second Virtualbox VM For the creation of this VM will we use the pre-existing Virtualbox template OracleVMManager311build365ova This VM will be our OVM Manager The normal way of installing Oracle VM Manager is to install a Linux Server (Oracle Linux or Redhat Linux) and then to install Oracle VM Manager from a ISO cdrom Here we use the VirtualBox template to save time
a) In VirtualBox go to gtFilegtImport Appliance and select the file OracleVMManager311build365ova
b) In ldquoAppliance settingsrdquo go to name and double-click OracleVMManager311build365 and change name to ldquoHOL9870_ovm-mgrrdquo Click on ldquoImportrdquo and click on Agree to accept License Agreement Note no need to change the RAM (4096 MB) and CPU (1 vcpu)
c) Wait for the import to complete (about 3 minutes)
d) Select the VM ldquoHOL9870_ovm-mgrrdquo and Click on ldquoSettingsrdquo o Go to Network and select ldquoHost-Only Adapterrdquo in Attached for Adapter 1
Note no need to set promiscuous mode to ldquoAllow allrdquo for the network interface as no VM will run on the manager
74 START AND CONFIGURE THE ORACLE VM MANAGER VM
a) In the VirtualBox admin console select the VM ldquoHOL9870_ovm-mgrrdquo and Click Start
b) Look at the VM console and wait for message ldquoNew Unix Passwdrdquo
c) Enter the following o For ldquoNew Unix passwdrdquo enter ldquoovsrootrdquo twice (same as Oracle VM Server password)
Ignore warning ldquoBAD PASSWORDrdquo this is because password is not secure o For static IP address enter ldquo192168563rdquo o For netmask enter ldquo2552552550rdquo (default) o For gateway enter ldquo192168561rdquo o For DNS server enter ldquo192168561rdquo o For hostname enter ldquoovm-mgroowcomrdquo

o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files

92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM

11
8 STEP 2 INSTALL ZFS STORAGE APPLIANCE In this LAB we will run main OVM operation on a ZFS Storage Appliance (iSCSI access) using the ldquoStorage Connect plug-inrdquo feature of OVM This feature enables the storage to be provisioned directly from OVM admin console (OVM Manager) simplifying the global management Since we donrsquot have real ZFS Storage Appliance for the lab we will use the ZFS SA simulator which is a tool we can run in a VirtualBox VM
81 CREATE A VIRTUALBOX VM FOR THE ZFS SA SIMULATOR
a) On your physical machine unzip the file
~HOL_OOWLAB3_HOL9870SunStorageVBoxzip This will create a directory named vbox-2011100118
b) In VirtualBox go to gtFilegtImport Appliance and select the file Sun ZFS Storage 7000ovf stored in the directory vbox-2011100118
c) In ldquoAppliance settingsrdquo o Go to name and double-click on Sun_ZFS_Storage_7000 Change name to
ldquoHOL9870_zfssardquo o Go to Systems and Change CPU to 1 o Click on Import
d) Wait for the import to complete (about 2 minutes)
e) Modify Storage settings
o Select the VM HOL9870_zfssa and Click on ldquoSettingsrdquo
o Go to Storage select Sun ZFS Storage 7000-disk2vmdk and click on icon to remove this virtual disk
o Repeat those actions for disk3 to disk16
o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings
14

o You should now see a message ldquosuccessfully configuredrdquo
83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files

25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon

37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM

The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

o Repeat those actions for disk3 to disk16
o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings
14

83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files

This will create 2 files
o OVMPluginAdminGuidepdf (documentation) o osc-oracle-s7k-012-45el5noarchrpm (RPM to install on the OVM Server)
d) Install the RPM file on the OVM server
From the physical machine open a new terminal $ scp osc-oracle-s7k-012-45el5noarchrpm root192168562tmp $ ssh root192168562
[rootovm-srv ~] rpm ndashivh tmposc-oracle-s7k-012-45el5noarchrpm
e) Fix a bug on the OVM Server (only present in OVM Server created from the OVA file build 365 o Modifiy the file initiatornameiscsi
rootovm-srv ] vi etciscsiinitiatornameiscsi
Add laquo InitiatorName= raquo in the front of the first line Ask your instructor if you are not familiar with vi
o The file should now look like InitiatorName=iqn1988-12comoracle66624642f860
o Restart the iscsid service and exit the terminal session [rootovm-srv ] service iscsid restart
[rootovm-srv ] exit
23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo

37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on

o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings
14

83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files

23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz

g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

o Repeat those actions for disk3 to disk16
o Select SATA Controller and click on icon to add a new disk
12
o Create a new disk type VDI Dynamically allocated name data-disk2 size 20GB
By default the ZFS SA simulator has 15 disks (15 virtual disks of 5 GB each) To get better performance on our laptop we will avoid stripping data on several virtual disks that are all stored in a single low performance disk (25rdquo 5400 rpm disk in laptops) Thatrsquos why we deleted the 15 5 GB data disks and created 1 single 20 GB disk
13
o Once created select SATA Controller and make sure to enable Use host IO cache (for optimized performance on the laptop)
f) Modify Network settings o Go to Network then Adapter 1 tab o Select ldquoHost-Only Adapterrdquo in ldquoAttached toldquo
o Click OK to exit Settings

83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi
o Finally click on Apply to actually create the iSCSI target and the iSCSI target group
22
84 INSTALL THE STORAGE CONNECT PLUG-IN FOR ZFS SA The installation of the storage connect plug-in consist of several actions o Installation of a RPM on the OVM server o On the ZFS SA installation of Workflows
(already done in the ZFS SA simulator we use) o On the ZFS SA create a dedicated user if the ZFS SA is shared with other applications
(not needed in the lab see plug-in documentation if interested) o On the ZFS SA create an iSCSI target and an iSCSI group to be used by OVM (done
previously)
a) On your physical machine Go in Applications-gtSystem open an new Terminal Windows unzip the file ~HOL_OOWLAB3_HOL9879ZFSSA_storage_connect_plugin_101_for_OVM_p13559479_120_Genericzip This will create 3 files

23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later

83 CREATE AN ISCSI TARGET AND ISCSI GROUP ON THE ZFS SA DEDICATED TO OVM
20
Before using the ZFS SA in OVM Manager we need to create dedicated iSCSI target and iSCSI group
o At the top of the screen go to Configuration SAN then iSCSI Targets
o Click on icon to create a new iSCSI target
o Give a name (alias) to the new iSCSI target ovm-iscsi-target for instance Note you can choose any name you want but you will have to enter the exact same name later in OVM Manager Leave all parameters to default value
o Click OK to create the iSCSI target
o You should now see the iSCSI target named ovm-iscsi-target
o Drag and drop the iSCSI Target just created in the iSCSI Target Groups panel (on the right) to create a iSCSI group named targets-0 according following instructions
Move the mouse pointer in front of the icon Press left mouse button
21
While keeping the left mouse button pressed move the mouse pointer to the right (below iSCSI Target Group named default)
Release the left mouse button
o Select the group targets-0 and click on the icon to edit it (to rename it) o Change the name to ovm-iscsi for instance and click OK
o You should now see both the iSCSI target ovm-iscsi-target and the iSCSI target group
ovm-iscsi

o Restart the iscsid service and exit the terminal session [rootovm-srv ] service iscsid restart
[rootovm-srv ] exit
23
9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN

c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab

g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles

9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server

94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon

37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab

37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)

9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd

97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles

9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab

g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM

91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles

910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611

9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles

97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later

g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped

9 STEP 3 OVM OPERATIONS
91 DISCOVER THE OVM SERVER IN OVM MANAGER
a) Connect to Oracle VM Manager web console
o On your web browser previously launched on your physical machine native OS open a new tab and connect to Oracle VM Manager console (using URL http1921685637001ovmconsole)
o Log in using user ldquoadminrdquo and password ldquoWelcome1rdquo
o You should now see the Oracle VM Manager Console
b) Discover the Oracle VM Server
o Click on the icon o Leave 8899 for the Oracle VM Agent Port o Enter ldquoovsrootrdquo for the Oracle VM Agent Password o Enter ldquo192168562rdquo for the IP Address o Click OK to launch the discovery o Wait a few seconds o You should now see the server named ovm-srvoowcom in ldquoUnassigned Serversrdquo
Click on the server to see server information (cpu Memoryhellip)
24
92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine

92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab

37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM

92 CONFIGURE OVM NETWORKS
a) Modify Networks Oracle VM has a number of network channels Server Management Live Migrate Cluster Heartbeat Virtual Machine and Storage Server Management Live Migrate and Cluster Heartbeat roles are automatically assigned to the management network when you discover Oracle VM Server For simplicity we will use a single network for all roles by assigning Virtual Machine and Storage roles to the default network o Click on the Networking Tab
o Select Network 192168560 and click on the icon to edit properties o In the network channels list check the boxes ldquoVirtual Machinerdquo and ldquoStoragerdquo
o Leave all other parameters to the default values by Clicking Next gt Next gt Next gt Finish
b) Create VNICs (Virtual Network Interface Cards)
The VNIC Manager creates Virtual Network Interface Cards (VNICs) which can be used by virtual machines as network cards You create virtual network interfaces by defining a range of MAC addresses to use for each VNIC o In the Networking tab click on ldquoVirtual NICsrdquo o Click on ldquoAuto-Fillrdquo and then ldquoCreaterdquo This will create 20 VNICs using Mac Addresses 0021f6000000 to 0021f6000013 You should now see those VNICs listed
25
93 DISCOVER THE ZFS SA IN OVM MANAGER USING THE STORAGE CONNECT PLUG-IN
a) On your OVM Manager console (in your web browser) go to the ldquoStoragerdquo tab
b) Right click on ldquoSAN serversrdquo then click on ldquoDiscover SAN serverrdquo
c) Enter the following information in the Discover SAN Server window Name zfssa Storage Type iSCSI Storage Server Storage Plug-in Sun ZFS Storage Appliance SCSI Plug-in Private Data OVM-iSCSIOVM-iSCSI-Target Admin host 192168565 Admin username root Admin Password ovsroot Access Host (IP) Address 192168565 Access Port ltLeave blankgt Note be careful to enter the exact same names (case sensitive) of the iSCSI target and iSCSI group you created previously in ldquoPlug-in Private Datardquo
d) Click on Next
e) Click on to add our server as an admin server for this storage
26
f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK

f) Finally click on Finish You should now see the ZFS SA storage server
27
94 CREATE 2 LUNS ON THE ZFS SA FROM THE OVM MANAGER
a) In OVM Manager console
o Go to the Storage tab select the new array zfssa (in San servers)
o On the right window click on to create a new physical Disk (new LUN) (Check that the selected ldquoPerspectiverdquo is ldquoPhysical Disksrdquo)
o Name is LUN0 10GB for the size o Click OK to create the LUN
b) Create another physical disk named LUN1 size is 10GB
c) You should now see 2 LUNs
d) From your browser On the ZFS SA admin console go to Shares LUNs and check that both LUNs were actually created
e) Enable write cache on the ZFS SA to get better performance
28
Enabling the write cache allows better performance on the ZFS SA for write IOs but will result in data losscorruption in case of abnormal shutdown on the laptop (which is OK since we are only building a demo environment here)
This is needed on ZFS SA simulator when virtual disks are written on 1 single slow physical disk (5400 rpm disk here on laptop)
On a real physical ZFS SA write cache is enabled by default as the array has a physical memory cache
o On the ZFS SA admin console edit LUN0 parameter by clicking on the pencil icon
o Go to Protocols and enable the Write Cache (in Write Cache Behavior)
o Click on Apply o Repeat those operations for LUN1
f) In OVM Manager present both LUNs to the default Access group according following instructions o Go back to OVM Manager in Storage tab o Select the zfssa SAN Server o Select Access Groups in Perspective box list o Select default and Right click o Select Present-Unpresent
g) Click on to Add LUN0 and LUN1 to Selected Physical Disks and click OK
29
h) In Servers and VMs Tab right click on server ovm-srvoowcom and select Rescan Physical disks (click OK to confirm rescan)
30
95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles

o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

95 CREATE A CLUSTERED SERVER POOL An OVM server pool contains a group of Oracle VM Servers which as a group perform virtual machine management tasks such as High Availability (HA) implementation of resource and power management policies access to networking storage and repositories The virtual machines running on a server can be ldquolive migratedrdquo to another server in the same pool Of course you need to have a shared storage system (NFS iSCSI FC) between all the servers of the pool The pool is called clustered in this case A clustered server pool needs a dedicated storage (NFS Filesystem or iSCSI Lun or FC Lun) with a size of at least 10 GB This server pool file system is used to hold the server pool and cluster data and is also used for cluster heartbeat A non clustered pool can have only 1 server In a clustered pool with at least 2 servers one of them is the called master server and is in charge of several admin tasks In case of failure on this server another will take the master server pool role and get this IP address Here for the purpose of this LAB our clustered server pool will have only one server THIS IS NOT A RECOMMENDED CONFIGURATION A pool should have at least 2 servers
a) Create a clustered server pool using the Oracle VM server
Here we will create a clustered server pool with a single server and we will use LUN0 of the ZFS SA as the shared Lun o In Oracle VM Manager go to tab ldquoServers and VMsrdquo
o Click on the 3rd
icon from the left ( ) to create a new server pool
31
o Enter the following answers - Name clusterpool - Virtual IP Address for the pool 192168564 - check ldquoClustered Server Poolrdquo
- Select Physical Disk for the storage server pool click on icon and select LUN0
- click on ldquoNextrdquo
o On the next window click on icon to add all servers (here only 1) to the pool and finally click on Finish
o Once created you should now see the server pool and our OVM server ovm-srv in it
32
96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS

96 CREATE A STORAGE REPOSITORY ON THE ZFS SA LUN Before creating we need to create at least one Storage Repository to store the VMs files but also ISO files templateshellip
o Click on the ldquoRepositoriesrdquo tab
o Click on to create a new Storage repository
o Enter the following information
o Repository Name myrepo
o Repository Location Physical Disk
o Server Pool is clusterpool
o Click on the icon and select LUN1
Note only unused and unpartitioned Luns can be used
o Click Next
33
Note The creation of the repository is going to take about 4 minutes because of IO
contention on the disk of the laptop During this time you can go on the ZFSSA admin
console and see activity (cpu Disk iSCSIhellip) in ldquoStatusrdquo
o Go back to OVM Manager and Click on to present this repository to all servers (here only 1) and finally click on Finish
o Wait a few seconds for the repository to be created
Note for non-NFS storage (which is our case here) an OCFS2 filesystem is created on the repository
o You should now see the new repository (click on to expand)
34
97 NOTES ON PVMHVM VMS AND TEMPLATES Notes on paravirtualized hardware virtualized VMs
o A virtual machine can have 3 types Hardware virtualized (HVM) An unmodified guest operating system
executes in complete isolation Instructions are trapped and emulated at the hardware level (Intel VT-xVT-i and AMD-V) allowing excellent performance thanks to limited overhead for guest modifications
Paravirtualized (PVM) A software interface similar but not identical to the underlying hardware is presented to the guest operating system Paravirtualization provides hooks for guest instructions so that complicated tasks can be performed by the host instead of the virtual machine where performance is worse Paravirtualization requires that the guest kernel is ported to be made aware of the virtual environment
Hardware virtualized with paravirtualized drivers (PVHVM) Similar to
HVM but with additional paravirtualized drivers to off load more processes to the host and increase VM performance This domain type is typically used to run Microsoft Windows guests with a limited performance penalty
o When installing Oracle VM servers in Virtualbox only Paravirtualized VMs can be created in Oracle VM servers
Notes on templates
o An oracle VM template is a ldquoVM imagerdquo pre-built that can be imported into Oracle VM and be used to easily and quickly create VMs identical to the template
o A template contains an OS image and generally contains databases and applications already installed and configured
o You can download many oracle VM templates built by Oracle on httpsedeliveryoraclecomoraclevm
o Those Oracle provided template have an Oracle OS (Oracle Linux or Oracle Solaris) o You can also create your own templates using the OS and applications you want o Here because of time constraint we will use a very simple template containing only
Oracle Linux 5 update 7 OS
35
98 SETUP AN HTTP WEB SERVER FOR ISO TEMPLATEShellip Importing objects ( Templates ISO images hellip) into Oracle VM can be done in several ways
o http web server using syntax httphost[port]pathfile o Anonymous ftp server using syntax ftphost[port]pathfile o Authenticated ftp server using syntax ftpuserpasswordhost[port]pathfile
In this lab we will use an HTTP web server (apache2) already running on the Oracle VM Manager
a) Create a directory to store the files that will be imported later o On your physical machine native OS open a new terminal o $ ssh root192168563 (password is ovsroot) o mkdir varwwwhtmlfiles
o chmod 777 varwwwhtmlfiles
o exit
Reminder if using Windows OS on your physical machine you will need tools to replace ssh and scp (putty and WinSCP for instance)
b) Transfert the file which will be needed later in the lab from your terminal o $ cd ~OOW_HOLLAB3_HOL9870 o $ scp OVM_OL5U7_X86_64_PVM_10GBtgz root192168563varwwwhtmlfiles
c) On your physical machine native OS start a web browser (Firefox during the OpenWorld lab)
and open the URL http192168563files to check the web server is working fine
d) Leave Firefox open you will need it later
36
99 IMPORT ORACLE LINUX 5U7 PVM TEMPLATE
a) Go to the ldquoRepositoriesrdquo tab
b) Expand ldquoRepositoriesrdquo and ldquomyrepordquo
c) Click on ldquoVM Templatesrdquo
d) Click on icon
e) Enter the URL of the file to be imported http192168563filesOVM_OL5U7_X86_64_PVM_10GBtgz
37
f) Click on OK to start the import
g) The import should take about 5 minutes o Import consists of 2 steps download and unpacking o You can follow progress in the ldquoJob summary panelrdquo o Once the import is finished you should see the template in rdquoVM Templatesrdquo
h) Select and Edit the template o Memory replace 2048MB by 1024MB o CPU replace 2 par 1
38
o In ldquoNetworksrdquo Tab add network ldquo192168560rdquo in ldquoSelect Ethernet Networksrdquo and click OK
910 CREATE AN OVM VM FROM THE OVM TEMPLATE
a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab

a) Before going on check that the template import is finished and make sure that all template modifications (CPU memory network) are done
b) In Oracle VM Manager web console go to ldquoServers and VMsrdquo Tab
c) Expand the server pool and right click on the server ovm-srvoowcom
d) Click on ldquoCreate Virtual Machinerdquo
e) Select ldquoClone from an existing VM Templaterdquo and enter the following information o Select ldquomyrepordquo as the repository o Select OVM_OL5U7_X86_64_PVM_10GBtgz as the VM Template o Enter ldquoguest-vmrdquo for the VM Name o Select ldquoclusterpoolrdquo as the Server pool
39
f) Click ldquoFinishrdquo to start VM creation Note Immediate VM creation on OCFS2 The VM creation should be almost immediate since the repository use OCFS2 filesystem and the reflink feature This avoids to copy all blocks of the template files but instead uses pointers to existing blocks in the new files (see details on the OCFS2 reflink feature on httpsblogsoraclecomwimentryocfs2_reflink)
g) You should now see the OVM VM in the status stopped
40
911 START THE OVM VM GUEST-VM
o Select the VM guest-vm
o Start the VM by clicking on
o Click on to launch VM console
o If needed allow popup in your web browser (Firefox during OpenWorld lab)
o Tell Firefox to use usrjavajre170_04binjavaws (installed with Java JRE) to
open jnlp files (Only needed the 1st time you open a vm console)
o Follow VM boot in the console
And enter information when asked - New unix root password ovsroot (ignore warning BAD PASSWORD) - Enable DHCP n - IP address 1921685611 - IP netmask 2552552550 - IP gateway 192168561 - IP address for DNS serveur 192168561 - Hostnamedomainname guest-vmoowcom
o Now you can log on this VM from a terminal in your Linux desktop
$ ssh root1921685611
o When ready shutdown the VM (to save laptop resources)
[rootguest-vm ] halt
This concludes this hands on lab
