Sorry i have just see the isssue.

in my code the ovs client connect the ovsdb use "localhost:6640"

    // connect to OVS
    ovs, err := libovsdb.Connect("localhost", 6640)
    if err != nil {
        glog.Fatal("Failed to connect to ovsdb")
    }

So you should start your ovs with the 6640 port in the same network namespace.
