Hi Nikhil, The right place for a question like this is probably the Quantum section of launchpad answers (https://answers.launchpad.net/quantum), or one of the OpenStack email lists.
That said, Luiz's response when you posted this to the dev list was correct: "Anyways, the Quantum OVS agent running in the Host fetches the MAC address from the OVS database and send to the Quantum. Have a look in here (get_vif_ports): https://github.com/openstack/quantum/blob/master/quantum/plugins/openvswitch/agent/ovs_quantum_agent.py " I don't really have anything to add beyond that.
