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?<br>

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>
