Open Stack

Hi Brent,
I've installed openstack using devstack, so I just created the local.conf
file before stacking.
I noticed that the br-int is created only when I set the network devices in
ONOS (it is connected to the nodes) and not when the during the set up of
the nodes.
I can attach my local.conf if it could be useful.
Thanks

Silvia
