CPU flags are always an issue, since a guest which starts on one host
expects to find at least the same set of processor features on the
destination too.

You can use the cpuid syntax in your cfg file to hide features on the
source domain, or I htink there is a way to do it host wide with a xen
command line parameter. it's a bit more manual with regular Xen as
opposed to XCP, andI'm afraid I'm not 100% sure of the details. I
suppose the docs and/or wiki ought to have something.
