[Bug 1453835] [NEW] Hyper-V: Nova cold resize / migration fails

 

Public bug reported:

Commit https://review.openstack.org/#/c/162999/ changed where the
Hyper-V VM configuration files are stored. The files are being stored in
the same folder as the instance. Performing a cold resize / migration
will cause a os.rename call on the instance's folder, which fails as
long as there are configuration files used by Hyper-V in that folder,
thus resulting in a failed migration and the instance ending up in ERROR
state.
