i've got the same problem, and i found the solution here on Fix Blue Screen Error, just for reference.

Tom,

Actually, vmotion boundaries between cpu chips may seem to have evolved some with the announcement of VMware’s Enhanced Vmotion feature, and the ability to migrate between Amd and Intel has certainly been in the spotlight recently, but the issue is still the same. That is, all vendor’s virtualization hosts check for like cpu families before live migration. If you decide to mask this safety check then any live migration is possible (all of hypervisors can do this). But this is just an ability and not a technical certainty. It may work 4 out of 5 times, but that 5th time when the application needs the instruction set that does not exist on the migration target the VM will blue screen.

If it has been shown possible to do VMotion between Intel and AMD processors, which are even more different than many Intel chips are different from each other, has VMotion evolved at all to the point where differences between Intel chips are less of an issue than they were in June when you blogged this??

Thank you, Tom
