Please shed light on me.Thank you very much. Hi, Since xen 3.3 there is a feature to configure the cpu xen exposes to the guests. I did some tests by exposing a generic 686 cpu and try live migration between Amd and Intel host cpus and it worked ok. There is some config file example into the xen tree that explains how to do that. This trick need much more testing if you want to do that in a production environment.
