[Openstack] [devstack] Question about the "OVS_PHYSICAL_BRIDGE" attribute defined in localrc

Hi,

When I have "OVS_PHYSICAL_BRIDGE=br-p1p1” defined in localrc, devstack creates the OVS bridge "br-p1p1".

localadmin at qa4:~/devstack$ sudo ovs-vsctl show
5f845d2e-9647-47f2-b92d-139f6faaf39e
    Bridge "br-p1p1"     <<<<<
        Port "phy-br-p1p1"
            Interface "phy-br-p1p1"
                type: patch
                options: {peer="int-br-p1p1"}
        Port "br-p1p1"
            Interface "br-p1p1"
                type: internal

However, no physical port is added to it.  I have to manually do it.

localadmin at qa4:~/devstack$ sudo ovs-vsctl add-port br-p1p1 p1p1
localadmin at qa4:~/devstack$ sudo ovs-vsctl show
5f845d2e-9647-47f2-b92d-139f6faaf39e
    Bridge "br-p1p1"
        Port "phy-br-p1p1"
            Interface "phy-br-p1p1"
                type: patch
                options: {peer="int-br-p1p1"}
        Port "br-p1p1"
            Interface "br-p1p1"
                type: internal
        Port “p1p1”     <<<<<
            Interface “p1p1"


Is this expected behavior?

Thanks,
Danny
