When I trying to test floating ip. I got followings on quantum-server

It seems glance bug is related.
https://bugs.launchpad.net/glance/+bug/1057325

However the fix is already in quantum...

[Nachi Ueno (nati-ueno)]

You can reproduce just using
quantum floatingip-create.

Actually, this was configuration problem.

Following fixes the problem

Uninstall rabbitmq
delete /var/lib/rabbitmq

reinstall rabbitmq

/etc/quantum/quantum.conf
rabbit_durable_queues = True

Fix proposed to branch: master

I am wondering why we need to do it, we have run quantum without it for a long time. We need to investigate more about this bug to make sure why we have this bug now.

Glance made a change about two weeks ago. This was the cause of all of the problems.

This has been dealt with by https://review.openstack.org/#/c/17469/
