we need to make sure before we bring up vlan interface on "configure_ironic_provision_network:723" that OVS_PHYSICAL_BRIDGE is up. otherwise we can fail (RTNETLINK answers: Network is down) This issue discover on a unique configurations I run different biridges for external network (PUBLIC_BRIDGE) and internal bridge (OVS_PHYSICAL_BRIDGE) so devstack don't seem to bring up ovs bridge.
