Hi Alisson,

Have you actually run Quantum with the OVS plugin enabled and the pointed
to the same database?  Running Quantum with the plugin is what should
create the tables.  The agent merely is a read-only client of those tables.
 Info on doing this for the OVS plugin is at:
http://openvswitch.org/openstack/documentation/
