First Patch Tuesday with Windows Server 2012 Hyper-V Patches – New version of Hyper-V Integration Services

Hyper-V Integration Services Upgrade

Yesterday Microsoft released some patches for Windows Server 2012 and Windows 8. In this wave Microsoft also included some fixes for Hyper-V and also updated the Integration Services to a new version.

Old Hyper-V Integration Services Version: 6.2.9200.16384
New Hyper-V Integration Services Version: 6.2.9200.16433

To check which version is installed in your virtual machine you can use Windows PowerShell: Get Integration Services Version of Windows Server 2012 Hyper-V Virtual Machines.

So if you are running Windows Server 2008 R2 SP1 virtual machines or later don’t forget to update your Hyper-V Integration Services on those virtual machines. If you are running Windows Server 2012 virtual machines you can normally patch those via Windows Update or WSUS to get the latest Hyper-V integration services.

If you run Windows Server 2012 Cluster Aware-Updating you can us the Self-Service update feature to patch your Hyper-V Cluster automatically.

In System Center 2012 Virtual Machine Manager was a cool new feature which allowed you to show the installed version of the Hyper-V Integration Services. In the normal Hyper-V Manager or Cluster Manager it was not possible to show the installed version. In Windows Server 2012 Hyper-V this has not changed, there is no GUI option to show the installed version, but there is Windows PowerShell. With the simple Get-VM cmdlet you can show the version of the Hyper-V Integration Services.

Linux Integration Services Version v3.3 for Hyper-V

Yesterday Microsoft released the Linux Integration Services for Hyper-V Version 3.3. The Installation is pretty much the same as with version 3.2. You can check out my blog post about Install CentOS on Windows 8 Hyper-V for the installation.

Linux Integration Services Version 3.3 for Microsoft Hyper-V Features

When installed on a virtual machine that is running a supported Linux operating system, Linux Integration Services for Hyper-V provides the following functionality:

  • Driver support: Linux Integration Services supports the network controller, and the IDE and SCSI storage controllers that were developed specifically for Hyper-V.
  • Fastpath boot support for Hyper-V: Boot devices now take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
  • Timesync: The clock inside the virtual machine will remain synchronized with the clock on the virtualization server with the help of the pluggable time source device.
  • Integrated shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager by using the “Shut Down” command.
  • Symmetric multiprocessing (SMP) support: Supported Linux distributions can use up to 4 virtual processors per virtual machine. SMP support is not available for 32-bit Linux guest operating systems running on Windows Server 2008 Hyper-V or Microsoft Hyper-V Server 2008.
  • Heartbeat: Allows the virtualization server to detect whether the virtual machine is running and responsive.
  • KVP (Key-Value Pair) Exchange: Information about the running Linux virtual machine can be obtained by using the Key-Value Pair Exchange functionality on the Windows Server 2008 virtualization server.
  • Integrated mouse support: The cursor is no longer bound to the VMConnect window when used with the Linux Graphical user interface.

Supported Virtualization Server Operating Systems

This version of Linux Integration Services supports the following versions of Hyper-V:

  • Windows Server® 2008 Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter (64-bit versions only)
  • Microsoft® Hyper-V Server 2008
  • Windows Server 2008 R2 Standard, Windows Server 2008 R2 Enterprise, and Windows Server 2008 R2 Datacenter
  • Microsoft Hyper-V Server 2008 R2
  • Windows 8 Release Preview (NEW)
  • Microsoft Hyper-V Server 2012 (NEW)
  • Windows Server 2012 (NEW)

Supported Guest Operating Systems

This version of Linux Integration Services supports the following guest operating systems and virtual CPU (vCPU) configurations:

  • Red Hat Enterprise Linux 6.0-6.2 x86 and x64 (Up to 4 vCPU)
  • CentOS 6.0-6.2 x86 and x64 (Up to 4 vCPU)
  • Red Hat Enterprise Linux 6.0-6.2 x86 and x64 (Up to 32 vCPU when used on a Windows 8 Release Preview or Windows Server 2012 host)
  • CentOS 6.0-6.2 x86 and x64 (Up to 32 vCPU when used on a Windows 8 Release Preview or Windows Server 2012 host)

Other supported operating systems (including SUSE Linux Enterprise Server 10 and Red Hat Enterprise Linux 5) should use the version of Linux Integration Services available at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=eee39325-898b-4522-9b4c- f4b5b9b64551.

Michel Lüscher from Microsoft Switzerland made a blog post back in April 2010 about how you install a Linux Guest system with the Integration Services in der Version 2.1



Cisco UCS Hyper-V Cluster – Important Updates for the Hyper-V Cluster – Part 9

Since we have installed our Microsoft Hyper-V Cluster on the Cisco UCS, Microsoft released some patches for Hyper-V, Windows and Clustering.

There are two really important Updates which I would recommend for Hyper-V Clusters.

  • The first is Service Pack 1 for Windows Server 2008 R2 and Hyper-V Server 2008 R2. Service Pack 1 brings a lot of Hotfixes for Hyper-V, Failover Cluster Feature and other Microsoft Server features. And it brings also a two new features called Dynamic Memory and RemoteFX.
  • The second one is a hotfix for Servers with Intel Westmere or Sandy Bridge and has a large amount of physical memory. Most of the Cisco UCS Blades will meet this configuration. You can get more information on this Hyper-V hotfix here.

This two updates will bring you a much better experience with your Hyper-V Cluster. It will improve performance, stability and it will add new features.



Time sync problems with Hyper-V Guests

If you have time sync problems with Hyper-V Guest Systems there is a simple solution for this.

Problems:

  • Time between Server and Active Directory Domain Controller is not correct
  • Can’t login because of this
  • Can’t add AD Users to local groups

Solution:

To solve this problem you have to disable Time Synchronization in the Hyper-V Integration Services for each guest. Then restart the Windows Time serviceon the guest. The guests will then correctly synchronize with a domain controller.
