By looking at your logs I can see two issues.

Can you ensure you have the rabbitmq server running? if not please fix it.

Also did you create br-ex bridge for the external connectivity?

Best, Ashok

If you have followed all the suggestions above, try the following, which works for me every time. Give your rabbitmq server about 5 minutes after startup, and RESTART all quantum services.

I have found that my system clogs the rabbitmq pipeline and thus when quantum starts, l3 and dhcp agents do not make their connections initially. If I wait, restart quantum services, all is well. Crappy workaround, but better than a non-working one.

Good luck.
