Windows Server 2012 Hyper-V: Configure VM Processor Compatibility for Legacy Operating Systems

Posted on May 8, 2013 by Thomas Maurer

Windows Server 2012 Logo

In Windows Server 2008 R2 you had a setting in the Hyper-V Manager GUI to enable Processor Compatibility for legacy operating systems such as Windows NT 4.0 Server or Windows Server 2000. In Windows Server 2012 Hyper-V this setting is gone from the GUI, but you can still change it via Windows PowerShell.

By using the Get-VMProcessor cmdlet you can list the virtual CPU information of your Hyper-V virtual machines.

As you can see you can find a property called CompatibilityForOlderOperatingSystemsEnabled which is set to “False” by default and this is okay in 99% of all cases. But even if Windows NT 4.0 Server or Windows Server 2000 is not officially supported by Microsoft anymore there are some customers which have to run some VMs with legacy operating systems and by changing this setting via Windows PowerShell and the Set-VMProcessor cmdlet you can allow VMs to run old operating systems.


Set-VMProcessor NT4VM -CompatibilityForOlderOperatingSystemsEnabled 1

And of course you can also change it back


Set-VMProcessor NT4VM -CompatibilityForOlderOperatingSystemsEnabled 0

Virtual Machine Backup and Recovery: Five Critical Decisions

Posted on May 6, 2013 by Thomas Maurer

Together with Symantec, Mahmoud Magdy (Microsoft MVP for Exchange Server) and Mikko Nykyri (VMware vExpert) we produced a whitepaper called “Virtual Machine Backup and Recovery: Five Critical Decisions”. This whitepaper covers an overview about virtualization and the challenges which come with the new workloads in terms of backup and recovery.

Because of the outstanding economy, flexibility, and service levels it offers, virtualization is transforming data centers at breakneck speed: by 2016, an estimated 80 percent of the world’s x86 servers will be virtual machines (VMs).1 But the speed of this transformation, along with the high resource utilization, ease of cloning, moving workloads, and other ways virtualization works its magic, raise challenges for “traditional” IT services and the teams that deliver them. Nowhere is the complexity that virtualization creates for traditional IT services more apparent than in backup and recovery, which participants in a recent Symantec survey ranked among their least-successful IT initiatives. This paper addresses five critical decisions organizations must make when building a backup and recovery plan to:

Maintain protection, visibility, and control of applications and data.

Maximize utilization of established infrastructure, processes, staff, and budget.

Use virtualization to improve backup and recovery processes.

Create an efficient, scalable, future-prepared backup and recovery environment.

Each issue is presented first in general terms that apply across IT environments, and then add comments for specific platforms, applications, or industries based on our individual experience as VMware® vExperts and Microsoft® MVPs.

You can download the whitepaper here: Symantec Virtual Machine Backup and Recovery: Five Critical Decisions

Make also sure you checkout the Google Hangout event on Fri, May 10, 7:00 PM – 8:00 PM.

Join a panel of virtualization experts including Microsoft MVPs Mahmoud Magdy & Thomas Mauer and VMware vExpert Mikko Nykyri as they discuss the white paper they co-authored and offer their thoughts on the most important things to consider for a virtualized server environment.

How to install System Center 2012 SP1 Update Rollup 2 for VMM

Posted on April 29, 2013 by Thomas Maurer

System Center Logo

Microsoft last week released the Update Rollup 2 for System Center 2012 SP1 – Virtual Machine Manager which includes a lot of fixes and improvements. If you want to update you can do this by using the Windows Update scenario or install it manually.

You have to uninstall the Update Rollup 1 for SCVMM (you can find more on the reason on Carmen Summers blog post). Windows Update will not show you the Update Rollup to before you have uninstalled UR1.

If you have downloaded the Update Rollup 2 via the Windows Update Catalog and have installed it manually, it’s recommended that you uninstall UR2 first, after that uninstall UR1 and finally install UR2 on a System Center 2012 SP1 installation without any Update Rollups installed.

After you have installed the Update Rollup 2 for Virtual Machine Manager, make sure you also update the Agents on the Hyper-V hosts.

VMM Agent Versions:

Update Rollup 1: 3.1.6011.0
Update Rollup 2: 3.1.6020.0

Btw. Remember to do this not only for the VMM management server, don’t forget the hosts where the VMM console is installed, like System Center App Controller.

System Center 2012 SP1 Virtual Machine Manager Update Rollup 2 available

Posted on April 24, 2013 by Thomas Maurer

Some days ago Microsoft announced the availability of System Center 2012 SP1 – Update Rollup 2, which included fixes for the whole System Center suite expect Virtual Machine Manager. Yesterday Carmen Summers wrote in her blog post that System Center 2012 SP1 Update Rollup 2 for Virtual Machine Manager is now available as well.

And KB2826405 and KB2826392 fixes around 20 issues with Virtual Machine Manager:

Virtual Machine Manager Server (KB2826405) and Administration Console (KB2826392)

Issue 1
The SUSE Linux Enterprise Server 11 operating system is missing from the Linux OS list.

Issue 2
A virtual machine cannot start after migration from Windows 7 to Windows 8 when the DiscardSavedState method is used.

Issue 3
A connection to the VMware virtual machine remote console session cannot be established.

Issue 4
Externally published VMNDs are filtered incorrectly.

Issue 5
When you remove a virtual switch extension property or edit a virtual switch extension manager connection string, a user-interface generated script also removes the HostGroups that are associated with VSEM.

Issue 6
UPPSet is not set on a physical network adapter when you add the network adapter to a team and when the network adapter is the first in the list of network adapters.

Issue 7
The default gateway is missing on a host virtual network adapter after you add a second physical network adapter to the logical switch.

Issue 8
Static IP pool that has the first address in a subnet fails for external network type.

Issue 9
VMM crashes during host refresher when VMM is unable to create a CimSession with the remote host.

Issue 10
Standard (legacy) virtual switch creation on Windows 8 hosts with management virtual network adapter does not preserve the IP properties of the physical network adapter.

Issue 11
The administration user interface crashes with a NullReferenceException error when you click Remediate on a host instead of a virtual network adapter.

Issue 12
The Virtual Machine Manager user interface displays a network adapter in a “Not Connected” state.

Issue 13
The Virtual Machine Manager stops responding with high CPU usage for five to ten minutes when you configure a VMND that has 2,000 network segments.

Issue 14
The host virtual network adapter property for a management adapter does not show port classification.

Issue 15
Live Migration fails at 26 percent when the network adapter is attached to an
isolated virtual machine network.

Issue 16
The Virtual Machine Manager Service crashes when a virtual machine that does not have a port profile is migrated to a cluster by using a logical switch that has a default port profile set.

Issue 17
Running Dynamic Optimizer on a cluster with incompatible host CPUs causes a Virtual Machine Manager Service crash.

Issue 18
The Host refresher crashes for any host that has the RemoteFX role enabled.

Issue 19
The minimum memory for dynamic memory greater than 32GB is a security risk.

Issue 20
The status of the network adapter is displayed as Not Connected in Virtual Machine Manager.

Windows Server 2012 Hyper-V: Configure VM Processor Compatibility via PowerShell

Posted on April 23, 2013 by Thomas Maurer

Windows Server 2012 Logo

If you have a mixed Hyper-V environment with Hyper-V hosts which have different CPU generations you may cannot live migration Virtual Machines from one Hyper-V host to another without setting the VM CPU Compatibility setting.

Note: I saw a lot of different environments where different generation of Intel CPUs were used, and most of the time Live Migration did still work. I would recommend to set this setting only if you really need it.

If you need to do this for multiple Virtual Machines you may better use Windows PowerShell to do this.

To do this you can use the new Hyper-V PowerShell module and the Get-VMProcessor and Set-VMProcessor cmdlet. With the Get-VMProcessor cmdlet you can get information about the virtual CPU of VMs. You can list this for all virtual machines running on one host by using the following command


Get-VMProcessor *

To change this setting for all virtual machines running on the Hyper-V host you can use the following PowerShell command. This does only working with virtual machines which are not running.


Get-VMProcessor * | Set-VMProcessor -CompatibilityForMigrationEnabled 1

If you want to shut down all the VMs first you can use the following command.


Get-VM | Stop-VM

If you just want to do this for a single VM you can use the following commands.


Get-VM TMG | Stop-VM

Get-VM TMG | Set-VMProcessor -CompatibilityForMigrationEnabled 1

To do a full automation you could do it the following way:


Get-VM * | Stop-VM

Get-VM * | Set-VMProcessor -CompatibilityForMigrationEnabled 1

Get-VM * | Start-VM

As you can see you can also find the “CompatibilityForOlderOperatingSystemsEnabled” property to enable Processor Compatibility for legacy Operating Systems in Windows Server 2012 Hyper-V for example Windows NT 4.0 Server or Windows 2000.
