No, Xen doesn't use virtio. At least not currently.
Xen PV guests always automatically use paravirtualized (optimized) drivers,
and these were available way before virtio drivers for kvm.
Xen also has 'pv-on-hvm' drivers for fully virtualized (HVM) guests.
These are not related to virtio either.
Recently the Xen pv-on-hvm drivers were accepted upstream in Linux 2.6.36 (rc).
