Open Stack

Hi all, 
I did a project with a TELCO, and used both Linux Bridge and OVS, with ML2 you can use multiple plugins and I do not recall ti have done anything special for the config. 

If you get stuck send an email, I can always check notes but Arindam, sent a detail steps so hopefully that will address your question.

I think several options in /etc/nova/nova.conf, /etc/neutron/plugins/ml2/ml2_conf.ini and /etc/neutron/neutron.conf should be modifed properly in order to use LinuxBridge instead of OVS.
