Comment 2 for bug 855030

ii python-kombu 1.0.4-2 AMQP Messaging Framework for Python
ii rabbitmq-server 2.5.0-1ubuntu2 An AMQP server written in Erlang

I added the carrot suggestion to nova.conf and it still fails about the same 1 in 20 or so vms not coming up but with a different error. I would be happy to help diagnose this if you have any other suggestions.
