Hi Sylvain,

Thanks for your answer.

No I am not. I am actually logged in the controller machine. I start the
l3-agent with sudo /etc/init.d/quantum-l3-agent start.

But I took a look at /var/log/quantum/dhcp-agent.log and I got this : (see
last log)
Like l3-agent, it complains about some interfaces that do not exist.

Here is the result of ovs-vsctl show on both the contoller node and the
compute node :

On the controller node which also runs as a network node:
