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

...oftware in question does benefit of using Hyperthreading.
