From my point of view this is a problem when doing a "live" migration
or move between Intel/AMD which is not easily possible. But doing a
"cold" image based migration should be possible if the guest OS is
able to boot on either CPU, no??
Strange thing is that i tested to restore the image on bare intel base
hardware and it works as expected at least with a older Core2. A image
created from this Intel machine does also crash like described inside
PVE 2.1, so it must be some special case for newer i3/5-2000 hardware
or a problem with newer KVM versions.

Would be really strange if cold migration is not possible. That's one
of the benefits of virtualization to unbound the OS from the hardware
