I think there was another very good reason why Red Hat chose KVM instead 
of Xen : the fact that Xen was not included in mainstream kernel. It was 
painful to maintain a patched kernel for it.

KVM is included in mainstream kernel since 2.6.20.

I personnally chose KVM as virtualization solution because I know it is 
in fact available in every Linux distribution. So if one fails, you can 
choose another, free, solution.
But with 3.0 kernel, it will perhaps also become true for Xen...
