Thanks, I can see that the front and backend devices are connected ok
and appear to be happy and the hotplug scripts were successful.

However I did notice that the device MAC address seems to have changed!
I can believe this could confuse things...

Does this issue go away if you specify
        vif=['bridge=xenbr0,mac=00:16:3e:42:ae:8f']
in your configuration?
