Hi Alisson,<div><br></div><div>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: <a href="http://openvswitch.org/openstack/documentation/">http://openvswitch.org/openstack/documentation/</a></div>

OK, I followed your suggestions (thank you all).<br>Now the command ($ python ovs_quantum_agent.py ovs_quantum_plugin.ini) returns the error below. The table really does not exist since I just created the database ovs_quantum (following the openvswitch plugin README). I can create it, but which columns this table should have?<div class="im">

you probably right, Soren. I will install ovs-* in the compute node and retry. I have ovs-* installed only in the controller. I will try it and give feedback. Thank you very much.</span></p>
