MAC address in OVS plugin

Asked by Nikhil S Menon

I have a doubt regarding OVS associated with Quantum. I have installed OpenStack with Quantum. In ovs-vsctl show Interfaces I can see MAC address and virtual interface ids in external_ids. Where did OVS get this information. Kindly help me in understanding the flow.

Best Regards,
Nikhil

nova sets this information when the VM is created. This is done using
something called a "vif-driver" in Nova. Vif-drivers for libvirt are
located here:
