all you need to do is create a bridge named "br-int", which is what<br>
the linux devices representing the vm nics will be plugged into.<br>
<br>
since you are using tunneling, there is no need to create a br-ethX<br>
and add a physical interface to it.<br>

p.s. btw, your config looks like its using database polling, which is<br>
not preferred. I'd suggest you use the default config, which uses RPC<br>
communication between agents and the main quantum-server process<br>
