processor may not work if migrated to a host with an AMD processor.
This problem is not specific to virtual machines and would also occur on physical
computers. For example, if you moved a hard drive with a Red Hat Enterprise Linux 4.0
installation from an AMD machine to an Intel machine, you would experience
problems trying to boot from that drive.
