Hi guys, I installed Neutron on the Ubuntu according to recommendations in the http://docs.openstack.org/trunk/install-guide/install/apt/content/install-neutron.install-plug-in.html (docs). But when I started the service I got:

2014-01-08 17:20:49.232 4617 ERROR neutron.common.legacy [-] Skipping unknown group key: firewall_driver

and commands in neutron-client return:

ExtensionManager' object does not support item assignment

What causes such a problem?
