list_instances and list_instance_uuids, as written in the Ironic driver, do not currently respect conductor_group paritioning. Given a nova compute is intended to limit it's scope of work to the conductor group it is configured to work with; this is a bug. Additionally, this should be a significant performance boost for a couple of reasons; firstly, instead of calling the Ironic API and getting all nodes, instead of the subset (when using conductor group), we're now properly getting the subset of nodes -- this is the optimized path in the Ironic DB and API code. Secondly, we're now using the driver's node cache to respond to these requests. Since list_instances and list_instance_uuids is used by periodic tasks, these operating with data that may be slightly stale should have minimal impact compared to the performance benefits.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
