I am migrating some Hyper-V based Virtual Machiness from their current server which is running Windows Server 2008 R2 over to another box that is running Windows Server 2012.
I exported all of the VMs from the 2008 R2 system into folders on a network share and imported them into the new 2012 server.
All of the VMs running Server 2008 R2 as their guest OS fired up fine.
The one VM that was running Windows Server 2003 R2 x86 as its guest OS says it started okay via the Hyper-V manager, but the system never boots. It just hangs at a black window with a flashing cursor.
I re-exported the VM from the 2012 server and imported it into a 2012 R2 Hyper-V server and get the same results when trying to boot it.
Both servers are Dell PowerEdge servers and both have Intel processors in them, so it's not an AMD vs Intel issue.
Anything special that I need to do to get the 2003 R2 based VM to boot under 2012/2012 R2?
