Server 2012: Cannot install Hyper-V role

Here is a problem without resolution so far:

I have a Microsoft Hyper-V 2008 R2 server in my lab. Now, when ewe have Server 2012 RTMed I decided to upgrade my infrastructure to Microsoft Hyper-V 2012.

Unfortunately it is NOT SUPPORTED. So I had no other choice than rebuild the host.

I rebuilt the host with Microsoft Hyper-V 2012 Server but the server never booted to OS properly (I mean the first boot after installation)

I tried to install a Windows Server 2012 Std. It was installed successfully and booted, but as soon as I enabled Hyper-V role the server asked for reboot and hung in starting state

I checked hardware prerequisites – everything look good. And I do not think we have much changed from 2008 R2…

 

So I rolled back to Microsoft Hyper-V 2008 R2 Server at this point and trying to find what it could be.

If anybody bumped to the same issue and know how to resolve it please let me know.
