Upgrading to Windows 2016 Hyper-V. What about the Virtual Machine Configuration?

July 24, 2015 Leave a comment

Well, at some point we will all upgrade to Windows 2016 Server. Server aside, what happens with the virtual machines itself?

One of the good advantages of the upgrade process is that it will not automatically upgrade the Virtual Machine configuration file. The virtual machine configuration version represents what version of Hyper-V the virtual machine’s configuration, saved state, and snapshot files it is compatible with.

After installing Windows Server 2016 and then importing or migrating (moving) a Virtual Machine from Windows Server 2012R2 the configuration version will remain the same: in Windows Server 2012R2 the VM configuration version is 5 and my advice for you is that you keep it as version 5 it the workload is important for you and you don’t want any risk. It is not clear yet if it will be possible to upgrade the virtual machine from Technical Preview to RTM.

On the positive side, by not upgrading the VM configuration version, the VM can be moved back to a server running Windows Server 2012 R2, if required. On the negative side, you will not have access to new VM features until you manually upgrade the virtual machine configuration version.

  • Version 5 VM’s can run on both Windows Server 2012 R2 and Windows Server 2016.
  • Version 6 VM’s can run ONLY on Windows Server 2016.

Also, in Windows 2016 Server the configuration changed from file (XML) and BIN + VSV extensions to VMCX (Virtual Machine Configuration) and VMRS (Virtual Machine Runtime State). The new format are also more resistant to storage corruption and more effective in r/w changes to VM configuration.

Summary of the VM configuration version

  • Server 2012 R2 has VM configurations version 5
  • Server 2016 TP1 – version 6.0
  • Server 2016 TP2 – version 6.2
If you decide to upgrade:

Windows 2012 : switching from Server Core to Server with a GUI

October 26, 2012 7 comments

I already blogged about this, but due the numbers of requests and confusion people are making, here we go again:

The Server Core does not have GUI and have a minimal footprint which helps to secure the server running Hyper-V role, for example. The benefit of using Core version, which is now the default version, is to reduced attack surface, reduced maintenance, consume fewer hardware resources than traditional FULL GUI Server and offer increased stability due to lesser running application.

But there is a trick : while you can switch between Core and Full and vice versa, if you installed Server Core version and then decide to go with a Server with a GUI, the payload that has the interface is not installed and you will need to provide the source path.

A server in Minimal Server Interface mode is about 300 MB smaller than the same server in Server with a GUI mode. A server in Server Core mode is about 4 GB smaller than the same server in Server with a GUI mode

Note: The recommendation/Best Practise is to install the Server Core installation unless you have a particular need for the additional user interface elements and graphical management tools that are included in the “Server with a GUI” option

When you install Windows 2012 Server Core and you want to switch it to Windows 2012 Full GUI version,

For servers with server core as the base installation:

To convert a server core installation  to a full operating system installation (GUI version)

1. Create an folder called C:\w2012\image

mkdir C:\w2012\image

2. Insert the Windows 2012 media into the optical drive and copy install.wim from

copy D:\sources\install.wim  C:\w2012\image

3.  Run the following command to retrieve the name or index number of the image:

Dism /Get-ImageInfo /ImageFile:C:\w2012\image\install.wim

4. Create an folder called  C:\w2012\MountPoint

mkdir C:\w2012\MountPoint

5. Run the following command to mount the offline Windows image (Note: index:2 = Standard Edition index:4 = Datacenter Edition) :

Dism /Mount-Image /ImageFile:C:\w2012\image\install.wim /index:4 /MountDir:C:\w2012\MountPoint  /ReadOnly

6. Upgrade the operating system by running the command:

c:\>Dism /online /enable-feature /featurename:Server-Gui-Mgmt /featurename:Server-Gui-Shell /featurename:ServerCore-FullServer /source:c:\w2012\MountPoint\windows\winsxs  

         or by using Powershell:

PS c:\>Import-Module DISM

PS c:\>Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart –Source c:\w2012\MountPoint\windows\winsxs

To convert a full operating system installation (GUI version) back to a server core installation

 c:\>Dism /online /disable-feature /featurename:ServerCore-FullServer
