[Gary Kotton <gkotton@xxxxxxxxxx>]

Hi,
I have managed to find the problem :). I have spent the whole day on 
this :(.
I was running devstack and the code executes ovs_quantum_agent.py. 
Whilst going through the mailing mails I came upon this mail and saw 
that you are calling quantum-openvswitch-agent.
I'll post a fix soon.
Thanks!
Gary
