Comment 11 for bug 855030

I am using mysql. In case it matters I am running nova-network on both nodes and also nova-api on both nodes as suggested by you here http://osdir.com/ml/openstack-cloud-computing/2011-09/msg00283.html

I did a fresh install using lucid and the same thing happens with one exception. On oneiric, the AMQP trace showing in the log is always associated with a vm never transitioning from pending to running. On lucid, I still sometimes see the error in the log but the VM does come up.

There must be some kind of race condition. Is there currently a test for nova that

1. Deploys a multinode configuration
2. Starts and terminates groups of vms for a long time, making sure they all end up running
3. Also fails if any error is written to a log file

Also, I did the latest install using ppa:openstack-release/2011.3 but I sometimes see things like this in the log. I find these messages in bug tickets that seem like they were fixed for diablo so I am not sure why I see them:

DBError: exceptions must be old-style classes or derived from BaseException, not NoneType
