Title:
Floating IP namespace not created when DVR enabled and with IPv6
enabled in devstack
Status in neutron:
Invalid
Bug description:
I just created a new devstack based on the latest Neutron code and the
l3-agent is failing to create the Floating IP namespace, leading to
floating IPs not working. This only happens when DVR is enabled, for
example, I have this in my local.conf:
Q_DVR_MODE=dvr_snat
When I allocate a floating IP and attempt to associate it with a
running instance I see this in the l3-agent log:
2015-03-04 20:03:46.082 28696 DEBUG neutron.agent.l3.agent [-] FloatingIP

That error means that no port for the external gateway will be created
along with the namespace where it lives.
Subsequent errors confirm that:

This is only happening with Kilo, but I don't have an exact date as to
when it started, just that I noticed it starting yesterday (March
3rd).
