Open Stack

Hi George,

Personally i have not dealt with this setup, but i can follow and assist 
you further.
According to the related bug report 
(https://bugs.launchpad.net/ubuntu/+bug/1243588)
"br100 is automatically set up by nova-network, you do not need to 
manually create it"
is that the case on your setup?

Best,
Thanassis
