Hi John,

Thanks for that suggestion, it got me passed that first step and into
another error :D
sqlalchemy.exc.ProgrammingError: (ProgrammingError) (1146, "Table
'neutron_ml2.agents' doesn't exist") 'ALTER TABLE agents ADD CONSTRAINT
uniq_agents0agent_type0host UNIQUE (agent_type, host)' ()

Which seems to be very similar to this BZ here:
https://bugzilla.redhat.com/show_bug.cgi?id=1061378

Cheers.
