I recently got following error when moving a VM from one Hyper-V 2012 Cluster to another Hyper-V 2012 R2 Cluster. The VM was shutdown at the time of moving. The error occured at the step where VMM imports the moved VM into the target host:
VMM cannot complete the host operation on the host.domain.com server because of the error: 'MV-1' could not be realized due to errors in its configuration file which could not be resolved. (Virtual machine ID C81AB5CD-1254-4D71-8021-7D866A6D8C8C)
Unknown error (0x8000)
Resolve the host issue and then try the operation again.
In the event log of the target Hyper-V server there are following entries in the Hyper-V-VMMs log:
Error 03.02.2015 14:01:39 Hyper-V-VMMS 24004
The virtual machine 'VM-1 Clean' is using processor-specific features not supported on physical computer 'host'.

The first event showed that there was a snapshot on the VM I tried to move. I should have checked this first. After merging the snapshot and starting the move again, VMM was able to move the VM and import it into the target host. There might be other issues that are causing this VMM error. In my case the merging the snapshot fixed it.
