Breaking old ideas

Hyper-V is right only for Branch OfficesHyper-V cannot be compare to VMware in terms of featuresHyper-V supports a very limited range of Guest OSHyper-V does not support high-performance network…

Breaking old ideas

Gartner:“ Microsoft has improved its server virtualization products to the point that IT leaders should assess their VMware investments and consider whether Microsoft makes sense. Compare acquisition costs, ease of management and functionality for the two vendors and take advantage of their competitiveness.” 1

the migration

• Check network / destination lun on Hyper-V Cluster• Check VM Health: no snapshot, restart the VM• Save Network configuration

During the

migration

• Remove VMware tools and VMware network card• Move virtual machine using VMM / Powershell scripts• Configure network and restart system

After the

migration

• Check connectivity, system and application logs, integration tools• Proceed application check

After secu

re time

• Remove virtual machine on VMware infrastructure (V2V is non-destructive operation)

… and its evolution

A case study …

Feature or functionality New or updated

Shared virtual hard diskHyper-V in Windows Server 2012 R2 Preview enables clustering virtual machines by using shared virtual hard disk (VHDX) files.

Resize virtual hard diskHyper-V storage has been updated to support resizing virtual hard disks while the virtual machine is running.

Storage Quality of ServiceStorage QoS enables you to manage storage throughput for virtual hard disks that are accessed by your virtual machines

Live migrationsHyper-V live migration has been updated to allow the administrator to select the optimal performance options when moving virtual machines to a different server.

Virtual machine generation

Virtual machine generation determines the virtual hardware and functionality that is presented to the virtual machine:

• Secure Boot (enabled by default)• Boot from a SCSI virtual hard disk• Boot from a SCSI virtual DVD• PXE boot by using a standard network adapter• UEFI firmware support

What’s new in Hyper-V in Windows Server 2012 R2

Feature or functionality New or updated 3rd party Software Defined Networking

Is supported by the extensibility of the virtual switch.

Automatic Guest ActivationCustomers running WS2012 R2 Datacenter can automatically activate their WS2012 R2 guests without using KMS. Works with OEM and volume licenses. Great for multi-tenant clouds.

Built-In NVGRE GatewayA multi-tenant aware NVGRE gateway role is available in WS2012 R2. Offers site-site VPN, NAT for Internet access, and VM Network to physical network gateway.

Clustering: Proactive Server Service Health Detection

The health of a destination host will be verified before moving a VM to another host.

Clustering: Protected Networks

Virtual NICs are marked as being on protected networks by default. If a virtual NICs’ virtual switch becomes disconnected then the cluster will Live Migrate that VM to another host with a healthy identical virtual switch.

Compressed Live MigrationUsing only idle CPU resources on the host, Hyper-V can compress Live Migration to make it quicker. Could provide up to 2x migrations on 1 GbE networks.

Cross-Version Live MigrationYou can perform a Live Migration from WS2012 to WS2012 R2. This is one-way, and enables zero-downtime upgrades from a WS2012 host/cluster to a WS2012 R2 host/cluster.

Dynamic Mode NIC TeamingIn addition to Hyper-V Port Mode and Address Hashing. Uses “flowlets” to give fine-grained inbound and outbound traffic.

Generation 2 VMA G2 virtual machine is a VM with no legacy “hardware”. It uses UEFI boot, has no emulated devices, boots from SCSI, and can PXE boot from synthetic NIC. You cannot convert from G1 VM (UEFI I am guessing).

What’s new in SCVMM 2012 R2 (source: http://www.aidanfinn.com)

Feature or functionality New or updated

HNV DiagnosticsA new PoSH cmdlet enables an operator to diagnose VM connectivity in a VM Network without network access to that VM.

HNV: Dynamic Learning of CAs

Hyper-V Network Virtualization can learn the IPs of VM Network VMs. Enables guest DHCP and guest clustering in the VM Network.

HNV: NIC TeamingInbound and outbound traffic can traverse more than one team member in a NIC team for link aggregation.

HNV: NVGRE Task OffloadsA new type of physical NIC will offload NVGRE de- and encapsulation from the host processor.

HNV: Virtual Switch extensions

The HNV filter has been included in the Hyper-V Virtual Switch. This enables 3rd party extensions to work with HNV CAs and PAs.

Hyper-V Replica Extended Replication

You can configure a VM in Site A to replicate to Site B, and then replicate it from Site B to Site C.

Hyper-V Replica Finer Grained Interval controls

You can change the replication interval from the default 5 minutes to every 30 seconds or every 15 minutes.

IPAMIP Address Management was extended in WS2012 R2 to do management of physical and virtual networking with built-in integration into SCVMM 2012 R2.

Live Resizing of VHDXYou can expand or shrink (if there’s un-partitioned space) a VHDX attached to a running VM. It must be SCSI attached.  This applies to Windows and Linux.

Live Virtual Machine Cloning You can clone a running virtual machine. Useful for testing and diagnostics.

What’s new in SCVMM 2012 R2 (source: http://www.aidanfinn.com)

Feature or functionality New or updated

Remote Live Monitoring Remote monitoring of VM network traffic made easier with Message Analyzer.

Shared VHDXUp to 8 VMs can share a VHDX (on shared storage like CSV/SMB) to create guest clusters. Appears like a shared SAS drive.

SMB Live Migration

This feature uses SMB to perform Live Migration over 10 GbE or faster networks. It uses SMB Multichannel if there are multiple Live Migration networks. SMB Direct is used if RDMA is available.  SMB Multichannel gives the fastest VM movement possible, and SMB Direct offloads the work from the CPU. Now moving that 1 TB RAM VM doesn’t seem so scary!

SMB 3.0: Bandwidth controlsQoS just sees SMB 3.0. New filters for default, live migration, and virtual machine allow you to manage bandwidth over converged networks.

Network DiagnosticsNew PowerShell tools for testing the networking of VMs, including Get-VMNetworkAdapter, Test-NetConnection, Test-VMNetworkAdapter, and Ping -P.

Virtual Machine Exports You can export a VM with snapshots/checkpoints

Virtual Switch Extended Port ACLs

ACLs now include the socket port number.  You can now configure stateful rules that are unidirectional and provide a timeout parameter. Compatibility with Hyper-V Network Virtualization.

vRSSVirtual Receive Side Scaling leverages DVMQ on the host NIC to enable a VM to use more than 1 vCPU to process traffic. Improves network scalability of a VM.

Windows Azure PackThis was previously called Windows Azure Services for Windows Server. It allows companies (such as hosting companies) to provide a self-service portal (with additional cloud traits) for their cloud.

Conclusion

Hyper-V and SCVMM: a case study and its evolution

Conclusion

Hyper-V 2012 R2 and SCVMM 2012 R2 do represent a MAJOR improvement in the Microsoft virtualization technologies portfolio

Old ideas must be forgotten and Microsoft technologies are certainly to consider when implementing a new environment, including for mission-critical systems

Hyper-V Network Virtualization is a little bit complex to understand but it’s certainly worthwhile: HNV is very powerful and ready for deployment in your datacenters
