What he said.

Also, xen to kvm migration is actually quite simple. Fully virt guests  
are of course a no-brainer, just some minor driver updates in the  
guest for slightly different hardware presented and to maximize  
performance (using the virtio disk/network/etc drivers). Xen para-virt  
guests are supported atop kvm using xenner.

And from what I've seen, most distros' Xen management tools are all  
libvirt/virt-manager based, and that's the exact same tools you use  
for kvm. At least in my Red Hat and Fedora world, that's the case...
