Open Stack

 Dear Thanassi,

 thank you very much for your interest! First of all let me inform you 
 that you are right and I am going with the first (a) approach 
 (nova-network).
 The guide I was following and the place on which the specific problem 
 arises is this one: 
 http://docs.openstack.org/havana/install-guide/install/yum/content/nova-network.html

 As you can see by yourself many people on the comment session below are 
 trying to understand how to move on with the br100 interface.

 In my case the interface wasn't created automatically (although in a 
 previous bug that I 've found the say that this was fixed but apparently 
 it hasn't been in my case). So I 've tried to move on and created the 
 br100 on the compute node without success. If I understand correctly, 
 according to your suggestion the br100 has to exist on the controller 
 node as well. Am I right? Should I create the br100 on both nodes?? Do 
 you have any further suggestions on how to assign floating (public) IPs 
 to the VMs? Currently I am having two nodes (controller + compute) with 
 two NIC interfaces each! One of them is used in order to connect 
 directly each to node to the other, while the other is used to connect 
 to the public LAN with a static IP. Any help and configuration schema 
 much appreciated!

 All the best,

 G.
