Open Stack

Hi all,

After hunting ghosts this weekend, I finally found the problem.

- Both my host and controller had firewalls set up blocking AMQP messages
- RabbitMQ binds to **all** network interfaces through :::5672.  Previously
I believed this to be only v6 addresses. I realize now that if the
flag IPV6_V6ONLY is not set, the IPv6 socket will serve both IPv4 and IPv6
traffic. It can be misleading when reading the output of netstat but that
is not an OpenStack problem

Thank you,
Viktor
