Hi Venkay, I was already following the user-guide. I've added my comments in line.
Thank you.

It's included the OVS switch who is part of the data network. I still cannot ping the instances creted in Openstack, and, again, except in the compute node that is also the Controller openstack, there is no ip address associated when I do ifconfig. > Moreover if I check the topology on dlux I can see only the instances > launched in the controller node.
