Thread-topic: 'lowest common denominator' cpuid feature set
I want to be able to test live migration... I have an intel box and an
amd box, so live migration between them won't 'just work'. From what
I've read though, I should be able to use cpuid to turn off all the cpu
features which might be different between them. Is this do-able? I'm
willing to accept any resulting loss of performance etc.

James
