Open Stack

I noticed this over the weekend as well.  I believe this is OVS trying to manipulate the tap device that is created for quantum-dhcp-agent.  If you have namespaces enabled, the tap device is not configurable from outside the netns, and that's what OVS is trying to do repeatedly.

I'm not sure if it's harmful or not - it doesn't appear to be.   The DHCP agent is working just fine.

Cheers,
Jim Chamings
