Virtualization Computing Hands-on Labs Training Manual

Step-By-Step Install Guide openQRM Data Center Management and

Cloud Computing Platform

By Kefa Rabah, [email protected] Nov 28, 2010 GTS Institute

Introduction

OpenQRM is the next generation, open-source Data-center management platform. It’s fully pluggable

architecture focuses on automatic, rapid- and appliance-based deployment, monitoring, high-availability,

cloud computing and especially on supporting and conforming multiple virtualization technologies.

openQRM is a single-management console for the complete IT-infrastructure and provides a well defined

API which can be used to integrate third-party tools as additional plugins.

OpenQRM server is a pretty neat datacenter management tool. You can use it to provision and manage

servers and cloud computing solutions. For example, if you’re just starting out with Linux server

provisioning and high availability OpenQRM is amazing product and can do wonders when setup properly.

In this hands-on lab session you’re going to learn how to accomplish this in style.

While OpenQRM is not a tool for public clouds It is geared towards people delivering private virtual

clusters or cloud capabilities. openQRM is a single-management console for the complete IT infrastructure

and provides a well defined API which can be used to integrate third-party tools as additional plugins.

What’s really interesting about OpenQRM is that it can suck up physical installations, create an image,

write that image to a SAN and then run the virtual instances on demand. I think the opportunity for

OpenQRM is to be able to suck those images up and then spit them out to cloud computing resources like

EC2, RightScale or Rackspace Cloud.

Hands on Lab Session

In this Hands-on lab session you’ll learn how to openQRM-server on Linux CentOS-5.5. It’s assumed that

you know how to install, configure and upgrade CentOS-5 server and have a good knowledge working

with Linux distros. You’ll learn how to install and configure openQRM. Manage Plugins. Build and deploy

images using openQRM. How to upload and run cloud images. In this lab you’ll learn how to build bundle

and upload Tinylinux and Ubuntu 9.04 images. Upon completion of this lab session you should have

gained skills and expertise to enable you to build and deploy your private cloud with Eucalyptus 2.0system on Linux. The entire lab session was performed using VMware to deploy the servers.

Part 1: Install Prerequisites

However, from the start, it seems like the installation of OpenQRM is kind of confusing, especially if you

use the official guide, which does not inform you that there are many other pre-requisites that must be met

before you can use their provided instruction. One needs to add few Yum repositories that are required by


http://www.gtechsi.ca/


http://www.openqrm.com/

http://www.openqrm.com/








3

the dependencies before you can use the openQRM yum install instruction – so here is the instruction that

I used to install it on the Linux CentOS 5 server:

openQRM hosts own packages for many distributions, including pre-built binary packages (please notice

that installation from the pre-built packages require an empty mysql password. It is recommended to re-

configure this after the installation in the openqrm-server.conf file).

1. Note if you just run the yum install without installing the prerequisites, then you’ll get the following info:

[root@cluster01 ~]# yum install openqrm-server-entire* -y

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

* addons: archaea.its.sfu.ca

* base: archaea.its.sfu.ca

* extras: archaea.its.sfu.ca

* updates: archaea.its.sfu.ca

Setting up Install ProcessNo package openqrm-server-entire* available.

Nothing to do

[root@cluster01 ~]#

2. So now let’s begin to install all the prerequisites.

Step 1: Install DAGC Repo

1. DAG repo contains certain packages such as Nagios. According to:

http://dag.wieers.com/rpm/FAQ.php#B

http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

2. This is how you should install the repo:

[root@cluster01 ~]# rpm -Uhv

http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-

1.el5.rf.i386.rpm

Retrieving http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-

release-0.3.6-1.el5.rf.i386.rpm

warning: /var/tmp/rpm-xfer.fyaFXf: Header V3 DSA signature: NOKEY, key ID

6b8d79e6

Preparing... ####################################### [100%]

1:rpmforge-release ####################################### [100%]

[root@cluster01 ~]#

Note 1: you can check the latest release from:






4

http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/

Note 2: Depending on your architecture, replace i386 architecture with x86_64.

3. You’re done with this section.

Step 2: Install Zabbex

4. OpenQRM will require Zabbex. The only place I found that has Zabbex RPMs is here:

http://fedoraproject.org/wiki/EPEL/FAQ#howtouse

http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

5. And you can install the repo by:

[root@cluster01 ~]# rpm -Uvhhttp://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-

4.noarch.rpm

Retrieving http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-

5-4.noarch.rpm

warning: /var/tmp/rpm-xfer.ipE6LL: Header V3 DSA signature: NOKEY, key ID

Preparing... ##################################### [100%]

1:epel-release ##################################### [100%]

[root@cluster01 ~]#


http://download.fedora.redhat.com/pub/epel/5/



Step 3: Install ASH

1. OpenQRM will require ASH to be installed. Unfortunately this package no longer comes with Linux

CentOS-5. You'll have to grab it from CentOS-4 package repository:

http://mirror.nexcess.net/CentOS/4/os/x86_64/CentOS/RPMS/

http://mirror.nexcess.net/CentOS/4/os/i386/CentOS/RPMS/ash-0.3.8-20.el4_7.1.i386.rpm






5

2. Or simply, run:

[root@cluster01 ~]# rpm -Uvh

http://mirror.nexcess.net/CentOS/4/os/i386/CentOS/RPMS/ash-0.3.8-

20.el4_7.1.i386.rpm

Retrieving http://mirror.nexcess.net/CentOS/4/os/i386/CentOS/RPMS/ash-0.3.8-20.el4_7.1.i386.rpm

warning: /var/tmp/rpm-xfer.LRvSW2: Header V3 DSA signature: NOKEY, key ID

443e1821

Preparing... ###################################### [100%]

1:ash ###################################### [100%]

[root@cluster01 ~]#


http://mirror.nexcess.net/CentOS/4/os/



Part 2: openQRM can be installed using yum.

Step 1; Install openQRM-Server

Note that you will need the openqrm-package-repository enabled for this to work e.g. create

"/etc/yum.repos.d/openQRM.repo" as follows:

1. Install OpenQRM repo. This is where OpenQRM packages will be coming from:

vi /etc/yum.repos.d/openqrm.repo

2. and add the following:

[openqrm]

name = Red Hat Enterprise $releasever – openQRM

baseurl = http://packages.linuxfellaz.net/centos5

enabled = 1protect = 0

gpgcheck=0

3. Save and close.

4. Finally, now that everything is in place, run:






6

yum install openqrm-server

Note: it will install all the required dependencies and execute the configuration script.

4. Login to the server by visiting the following:

https://<ip address>/openqrm/

Note: the username you'll need to login is "openqrm" and password is also "openqrm", as shown

in Fig. 1.

Fig. 1

5. You should now be logged into your openQRM server, as shown in Fig. 2.






7

Fig. 2

6. Ensure that MySQL server and openQRM-server start during host server bootup.

chkconfig openqrm-server on

chkconfig mysqld on

7. You can stop/start/restart your open server, as follows:

service openqrm-server stop

service openqrm-server start

service openqrm-server restart






8

Fig. 3

Note: always do ensure that MySQL server is also running:

8. If everything went well up to this point, then you now have a working openQRM setup with no

resources and no virtual environments but at least one boot image

9. You’re done with this section

Step 2: openQRM-Server Layout

1. From the left pane under Base heading, click Appliance Overview, by default is empty when you

first install the server, as shown in Fig. 4.

Fig. 4

2. From the left pane under Base heading, click Events Event list, gives you an overview what’s

happening or going on with your server, as shown in Fig. 5.






9

Fig. 5

3. From the left pane under Base heading, click Images Overview, gives you the list of images

installed on your server, as shown in Fig. 6.






10

Fig. 6

4. From the left pane under Base heading, click Kernels Overview, gives you the list of existing host

kernel on your server, in this case Linux Xen is running as default as shown in Fig. 7.

Fig. 7






11

5. From the left pane under Base heading, click Resources Overview, gives you the list of existing

resources running on your server, in this case openQRM is running, as shown in Fig. 8.

Fig. 8

6. From the left pane under Base heading, click Storage Overview, by default is empty when you

first install the server, as shown in Fig. 9.






12

Fig. 9

7. From the left pane under Base heading, click Documentation, here you have a list of documents that

you can browse/read to learn more about your openQRM-server, as shown in Fig. 10.

Fig. 10






13

Step 3: openQRM Plugins Layout

1. From the left pane under Plugins heading, click Plugins Plugin Manager, here you have a list of

plugins that you can use to manager your openQRM-server, as shown in Fig. 11.

Fig. 11

Note: click the plus sign icon to enable a plugin. It indicates the plugin is disabled.

Note: click the cross sign icon to disable a plugin.

Note: click the pause sign icon to start a plugin. It indicates the plugin is paused..






14

2. For example at the moment we have enabled but not started Xen plugin, i.e., its paused, as shown in

Fig. 12. Click on the pause sign icon to start Xen.

Fig. 12

Note: click the arrow sign icon to stop a plugin. It indicates the plugin is running.

3. When we enable Xen plugin, a new folder icon Virtualization is added to Plugin list, as shown in

Fig. 13.

Fig. 13


Step 4: Activate DHCP, TFTP, Storage Plugins

1. After setting up the openQRM Server system and pre-configuring the Hypervisor- and storage-

components the initial openQRM environment now can be started by enabling and starting the

following plug-ins:






15

• dhcpd - automatically provides and manages the ip-addresses in the management- and storage-

network

• tftpd - provides the network-boot-manager for a centralized kernel- and boot-management

• lvm-storage - provides 3 different storage- and deployment-types (lvm-nfs, lvm-iscsi and

lvm-aoe)

2. Also please do ensure that you enable the Virtualization plug-in for the selected Hypervisor

Technology (e.g. xen or kvm for this example setup):

• xen - integrates with Xen-Hypervisors and provides 2 new resource types : "Xen Host" and

"Xen VM"

• kvm - integrates with KVM (kernel virtual machine) and provides 2 new resource types : "KVM

Host" and "KVM VM"

3. The final picture should look like shown in Fig. 14.

Fig. 14

Part 3: Using openQRM Server

The first example is how to create an NFS storage section; however, for production environments it’s

recommend that you use iSCSI, but for this lab session we’ll NFS storage. To do this, perform the

following procedure:

1. Login to you openQRM web dashboard if you haven’t done so yet.

2. From the left menu under the Plugins click Plugin Manager and from then enable "nfs-

storage" plugin.

3. Next, from the left menu under Base heading click Storage Overview and then click on the New

Storage tab, as shown in Fig. 15.

Fig. 15

4. From Fig. 16, from right pane under New Storage heading, under Deployment drop-down menu,

select NFS Storage, and then select the host server by clicking the respective radio button and

finally click on the Select button. to continue

select root device from the drop down. (Set this root devices same as our logical location

"/dev/VolGroup00/cloud_lv")

3. Then deployment parameter as: IMAGE_ROOT_DIR="/devl/VolGroup00/cloud_lv"

What Just Happened?

2. Our logical volume "cloud_lv" mapped as "root fs".

Fig. 28






28

4. Now we have an empty logical volume that needs to be filled with server template (or Virtual

Appliance), see Fig. 29.

Fig. 29


Step 4: Download & Untar Ubuntu 10.10 LTS

1. Now logical volume (/dev/VolGroup00/cloud_lv) needs to be filled template.(virtual appliance)

(we have downloaded ubuntu 10.10 template from www.stacklet.com)

2. Move this .gz file to /dev/VolGroup00/cloud_lv and decompress it.

What Just Happened?

3. We have filled the logical volume with template.

Step 5: Creating Xen VM

1. We now need to create Xen virtual machine

2. Go to Base Appliance Overview and select "New Appliance" tab

3. Choose local openqrm server (192.168.83.179) from the displayed Resource list.

4. Provide appliance name ("cloud_appliance") and set resource type as "Xen Host" from the

dropdown and save it.

What Just Happened?

You have created a Xen Host appliance to create Xen VM's


Step 6: Configure Xen plugin

1. Go to Xen-plug-in.

2. Choose the Xen-host from the list and Now you can click on "+VM" and set VM name ("Cloud_VM"),

disk, swap size and click create.
