Description Stephen Gordon 2015-11-25 20:19:48 UTC

+++ This bug was initially created as a clone of Bug #1285523 +++

Description of problem:

In RHEL OpenStack Platform 8 we wish to include support in the fence compute (Nova) agent support for:

- The new OpenStack mark host down API call, where available, for telling NOva the host is down.
- Only evacuating instances that are marked evacuable in their associated image properties or flavor extra specifications.

Initial upstream work has been done:

https://github.com/ClusterLabs/fence-agents/commit/e3d7ccd652edb5d0bd60c210b029ce73c5fa27e9

https://github.com/ClusterLabs/fence-agents/commit/d9f2f483611253ece7fb097a9119de20a22d9111

...but an additional change is required to ensure *only* those instances that were marked evacuable are evacuated. Currently if *no* instances are found to be marked evacuable then *all* instances are considered evacuable which is not the behaviour we want out of the box (for those that do want all instances evacuated, tagging them as such is a simple matter).
