# Add a physical interface to your virtual bridge for connectivity off box.
# If your rootfs is nfs mounted (on eth0), you will die after attaching it
# to the bridge.

ovs-vsctl add-port br-int eth0
# Zero out your eth0 interface and slap it on the bridge interface.

(You can then check that the connection works.)

# and you reboot, it will still be messed up. Destroy the bridge,
# then add a route, or reboot.
