Open Stack

Maybe one thing I to add, This is a devstack post-config. So what was
taken in addition from the default config is: 

[ml2] 
type_drivers = flat,gre


[securitygroup]
firewall_driver =
neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver



And I predefined the bridge br-ext.


Good Luck and enjoy your weekend!
