Thanks for the information. I just tried doing it with a VM with only 2 cores and it has been working fine. So it seems that it may be specific to the number of cores that are involved. I'll try with 4 to see if that works ok. Thankfully we don't have many 8-core machines but we still have the need to migrate them for maintenance.
Does this core-specific information help to figure out what the problem is?
