commit 378bef70db4ca7437d716ac3e1b11a2a789f919f Author: Surya Seetharaman <[email protected]> Date: Tue Mar 27 13:00:21 2018 +0200 Scheduling Optimization: Remove cell0 from the list of candidates This patch removes cell0 from the list of loaded cells in the cache before scheduling. Doing this improves performance slightly.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1759306 Title: Scheduler host manager does not filter out cell0 from the list of cell candidates before scheduling Status in OpenStack Compute (nova): Fix Released Bug description: Currently the nova scheduler does not filter out cell0 from the list of cells that it considers for scheduling. Since cell0 does not have any computes and is only a graveyard cell, it should be filtered out from the global cell cache that is maintained by the host_manager (https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L639) and should not be a candidate cell for scheduling. It will anyways be filtered out due to not having computes every time during scheduling, however if this is done earlier on, it will optimize the scheduling.
