OK, I followed your suggestions (thank you all).
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?

 Hi:

         Try to run it with the absolute path, such as:



root@nova-quantum1:/home/robin/work/quantum-2012.1~e2~20111209.f8152#
python ./quantum/plugins/openvswitch/agent/ovs_quantum_agent.py
./etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini

Connecting to database "ovs_quantum" on 192.168.0.166, user:root ; pwd:

I have a dual node (Controller and Compute) OpenStack setup, working fine.
But i want to configure quantum for NaaS. I follow all steps of quantum
administrator guide, and installed it in the controller-node. To configure
the OVS plugin we must copy  ovs_quantum_agent.py and
ovs_quantum_plugin.ini to the compute-node and launch the command

$ python ovs_quantum_agent.py ovs_quantum_plugin.ini

but it returns me the error

Traceback (most recent call last):
  File "ovs_quantum_agent.py", line 297, in <module>
    plugin = OVSQuantumAgent(integ_br)
  File "ovs_quantum_agent.py", line 175, in __init__

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.

Please share the exact error message from after installing openvswitch.



Best regards,

Soren Hansen

When i first had the problem i did not have it installed.
But then i installed it

root@nova-controller:~# ovs-ofctl -V
ovs-ofctl (Open vSwitch) 1.3.0
Compiled Dec 20 2011 18:08:01
OpenFlow versions 0x1:0x1

but the problem persists.

It's complaining that it can't find ovs-ofctl. Did you install openvswitch?
