It's in progress. The xen code in the code base seems to have problems though, recent testing showed that it'll only work with recent linux kernels. Older linux kernels and windows guest drivers do not work correctly. So this is not just about enabling kvm support, but also about figuring why things are not working correctly on xen ... cheers, Gerd
