Comment 5 for bug 1232965

The RHEL/Centos/Fedora install guide currently leads you to this bug:

"Regardless of which firewall driver you chose when you configure the network and compute nodes, set this driver as the No-Op firewall. The difference is that this is a Nova firewall, and because Neutron handles the Firewall, you must tell Nova not to use one."

Looks like a show stopper to me.
