I can see how this can work if the NFS server is on the local subnet:
Linux is quite happy with two interfaces having the same IP. However, if
you're trying to transfer routes from eth0 to xen-br0 I'm not sure its
possible to do it 'atomically'.

Please could someone experiment and post a patch to vif-bridge.

Thanks,
Ian
