Re: [Xen-users] multiple vif's/bridges
Might be worth checking all the MAC addresses (the VIFS at both "ends" (the
dom0 vif devices and the domU eth devices). Might as well check the "eth"
devices in dom0.
Can you post those MAC addresses, plus your domain configs where they are set.
If you get clashes in the MAC addresses, all sorts of weird behaviour can
happen!
Cheers,
Mark
