But once you have your XEN DomU config file converted to KVM you could in effect just reboot the Dom0 into a standard kernel and use KVM.
Unless of course you're only moving one DomU to KVM then it wouldn't work.

hypervisor a problem? Maybe this has changed but I thought in order to be
able to use KVM you first have to disable the Xen hypervisor and boot into
the regular Kernel.
