The commit c1ccc1a3165ec1556c605b3b036274e992b0a09d introduced a regression when NUMA live migration was done on shared storage The live migration support for the power mgmt feature means we need to call driver.cleanup() for all NUMA instances to potentially offline pcpus that are not used any more after the instance is migrated away. However this change exposed an issue with the disk cleanup logic. Nova should never delete the instance directory if that directory is on shared storage (e.g. the nova instances path is backed by NFS). This patch will fix that behavior so live migration will function Closes-Bug: #2080436 Change-Id: Ia2bbb5b4ac728563a8aabd857ed0503449991df1 (cherry picked from commit 035b8404fce878b0a88c4741bea46135b6af51e8)

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:
