I have been playing with the AggregateInstanceExtraSpecs filter and can't get it to work.

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
