commit 3d6fac8dea940b62e88f239c5615acc500b74f05 Author: EdLeafe <[email protected]> Date: Wed Dec 9 17:51:52 2015 +0000 Don't load deleted instances When the HostManager starts up, it loads the instance information for all of the compute nodes. The call it uses, though, includes the records for deleted instances, which are not needed, and which can cause performance issues for large deployments. This patch adds a filter on deleted records.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1524421 Title: Host Manager reads deleted instance info on startup Status in OpenStack Compute (nova): Fix Released Bug description: In Kilo we added the ability of the HostManager to track information about the instances on compute nodes, so that filters that needed this information didn't have to constantly make database calls to get it. However, the call that is used by HostManager will return deleted instance records, which is not useful information and degrades the performance. In a large deployment, the overhead of loading the records for thousands of deleted instances is causing serious performance issues.
