2008 R2 VM crashes after converting is disk from a VHDx to a VHD format - Hyper-V 2012
Posted on 2013-10-27
I've ran into a problem where I want to convert a virtual MS 2008 R2 DC (which is running on a 2012 HV host) from the VHDX disk format to a VHD format; the VM was created with a VHDX disk and this might be the problem?
The GUI convert process appears to complete and the .VHD is created but when I link it up to the VM and attempt to boot I get errors C00002E2 and 0xC000001, I've not tried the PowerShell convert process yet but I'd expect the same result.
WHY am I doing this: I'm using Altaro for backing up and it refused to backup this 2008 VM with an error stating it can't find the .VHD files - I guess this is because the VM was created with VHDX disks and not VHD. (opps)
I could always rebuild but I'd like to know why and if anyone else has come across this.
I'm experienced but not so much with Hyper-V, so I wonder if I'm missing something.
