That should work, it tells all of the nova services to attach their virtual nics to that bridge name. Essentially the same as doing it through brctl. If that doesn't work please let me know.

I want to know what should i modify in nova.conf to allow new instances to see my openvswitch bridge 'br0' which is already configured. Does flat_network_bridge resolves my problem and how? thanks.
