Thats very interesting, ive got a set of domUs that have flakey
networking, all of which have a 'fixed' mac...

They just drop off the network, arp tells me the mac address is
incomplete, from both domU and dom0

Sometimes they recover after a while

im gonna try letting Xen allocate macs and see how it goes
