Description RHOS Integration 2013-12-12 13:25:11 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/graceful-shutdown.

Description:

Enable Nova services to be terminated gracefully.  Disable processing of new requests, but allow new requests to complete before terminating the process.

During a software upgrade, this would allow service instances to be swapped out, while still completing existing requests.

Steps:
1) Disable message "listening".
2) Disable periodic task timer.
3) Wait for existing requests and periodic tasks to complete.
4) Kill process.

Moving to POST based on upstream status (Implemented).
Comment 5 Nikola Dipanov 2014-03-21 15:34:10 UTC 
The support for this was added in early Icehous, but was broken by accident as can be seen from the linked upstream bug.

Upstream patch for the bug is also attached and should be part of the RC-1 tarballs.
