Essex3 : AttributeError: 'Connection' object has no attribute 'connection_errors'

asked 2012-02-14 09:46:08 -0600


I am trying to setup an OpenStack Cloud environment from the essex-3 packages available on launchpad.

I have an issue when I try to start nova-scheduler and nova-network (see below). kumbo == 1.0.4 amqplib == 0.6.1

Thank you very much for your help.

Regards, Jérôme

Hello again,

In fact, the problem is solved now.

But I think, there is a bug... let me explain.

When I set up Glance (from the packages provided on launchpad essex3), it setups automatically Kombu == 2.0.0. And that was the problem. After a revert from 2.0.0 to 1.0.4, nova was OK again.

Thank you. Jérôme
