We currently have Hyper-V 2008 R2 with KB2744129 installed.  I am looking to build a Windows Server 2012 R2 VM within the next couple of weeks, which is months ahead of our planned upgrade to Hyper-V 2012.  Microsoft's document about Hyper-V supported client operating systems mentions that Windows 8 & Server 2012 client VMs are supported if you have KB2744129 installed.  However, there is no explicit mention of Windows 8.1 or Windows Server 2012 R2.  Additionally, the editions column for Server 2012 only lists Enterprise and Datacenter editions as being supported.  Considering that this document was updated 11/18/2013, does this mean that only non-R2 Enterprise & Datacenter versions of 2012 will work and/or be supported?

Yes, they are supported.

Since Microsoft wants us to move faster to Windows 2012/8 they may not update fully their documents related to the older versions.

Also, there is no Enterprise edition of Windows Server 2012 – only Standard and Datacenter.

Svet,
Just to clarify, are you talking about the original versions of Windows 8 & Server 2012, or are are you talking about Windows 8.1 and Server 2012 R2 being supported as guests?  Microsoft's documentation speaks in the affirmative about Windows 8 & Server 2012, but omits any reference to Windows 8.1 or Server 2012 R2.

I had a test server Windows Server 2012 R2 running without any issues on the top of Windows Server 2008 R2 Hyper-V. I have not test Windows 8.1 yet but since it shares the same kernel I presume it will be OK.

Just give it a try and do some tests with your applications. You can download the evaluation version of both products from Microsoft web site.

Do not, however, try to install the Integration services from Windows Server 2008 R2 on the top of 2012 R2 or 8.1. They already have a newer version integrated.
