Bug Description
This bug report is here to be able to link the patch (to be commited) to the bug reported in the mailinglist by Sam Morrison
I quote:
---------
I have been playing with the AggregateInstan
In our staging environment it works fine with 4 compute nodes, I have 2 aggregates to split them into 2.
When I try to do the same in our production environment which has 80 compute nodes (splitting them again into 2 aggregates) it doesn't work.
nova-scheduler starts to go very slow, I scheduled an instance and gave up after 5 minutes, it seemed to be taking ages and the host was at 100% cpu. Also got about 500 messages in rabbit that were unacknowledged.
We are running stable/folsom. Does anyone else have this issue or know if there have been any fixes in Grizzly relating to this? I couldn't see any bugs about it.
Thanks,
Sam

A brief discussion followed, indicating this appears to be a bug indeed, not a missing index. We're experiencing and seeing the same behavior, and I think I've found the root cause.
From what I can see, there's a many-To-many relation defined in nova/db/
