Can you try "xl -vvv ..." for more debugging. Also have a look
under /var/log/xen for any relevant logs.

Is /etc/xen/scripts/vif-bridge present? If so then a useful debug
technique can be to add to the top
        exec >>/tmp/hotplug.log 2>&1
which will cause the script output to be logged to /tmp/hotplug.log
which might give a clue.

Ian.
