Comment 5 for bug 1277204

Thanks Andera,

I've added what I found so far to the bug report. I think there are at least two issues here:

Setup.cfg has mis-spelt the backwards compatibility names

But even using the mis-spelt name produces a stack trace when Nova tries to send a message

> 1) Create a devstack system

> 2) Add the following lines to the [DEFAULT] section of nova.conf:

> notification_topics = notifications,monitor
> notify_on_state_change = vm_and_task_state
> notify_on_any_change = True
> instance_usage_audit = True
> instance_usage_audit_period = hour
>
> 3) Restart all the n-* services

> 4) Look at the info queues in rabbit

> notifications.info 15

> 5) Create an instance
