all you need to do is create a bridge named "br-int", which is what
the linux devices representing the vm nics will be plugged into.

since you are using tunneling, there is no need to create a br-ethX
and add a physical interface to it.

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