I am trying to connect a Nox controller to an OpenVswitch 1.4.0 on my

My system settings are:

*sudo ovs-vsctl show*
    Bridge "br0"
        Controller "tcp:"
        fail_mode: standalone
        Port "eth0"
            Interface "eth0"
        Port "br0"
            Interface "br0"
                type: internal
        Port "tap0"
            Interface "tap0"
        Port "tap1"
            Interface "tap1"

There are no flows that I can see..
*sudo ovs-ofctl dump-flows br0*
NXST_FLOW reply (xid=0x4):

I am running the controller at the port 6633 in the same machine...But, the
following two are the only two message I see when the controller starts:

*sudo ./nox_core -v -i ptcp:6633 pyswitch*
00001|nox|INFO:Starting nox_core
00002|nox|INFO:nox bootstrap complete

I am not sure why the bridge br0 is not able to connect to the Nox
If anybody has tried this before, could you please let me know any pointers
to as to where its going wrong?

Thank you,
