VirtIO (vtnet) so far seems to work for migrates, and work for routing=20 traffic to other DomU guests - so I'm continuing to test that now as a=20 workaround (i.e. test with OpenVPN etc.) The only thing I've noticed with it is that established TCP sessions=20 'through the DomU' tend to die during the migrate (i.e. the DomU 'lands' at = the destination node - but any transfers in progress stall - there's a=20 50/50 chance they recover) - but if I migrate the Windows DomU that's=20 actually got the download in progress, the session stays up - hence more=20 testing needed. -Karl
