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