FYI I just tested these under Fedora 11 x86_64. I was running Xen 
inside a KVM guest for added fun. There were mixed results depending
on the disk/net config I launched KVM with.

 - disk=ide, net=rtl1839  -> Boots & works nicely
 - disk=virtio, net=rtl8139 -> hangs in kernel when init USB
 - disk=ide, net=virtio -> kernel panic trace in networking code

I was impressed that Xen + Dom0 pv_ops worked at all inside KVM really :-)
Even this limited funtionality is great progress... I'll attach the logs
for the failed boot attempts in case anyone can interpret them.
