so [4] is actually related to the following bug (it is linked on the
review):

https://bugs.launchpad.net/nova/+bug/1416132

The proposed patch is, as was discussed in some details on the patch - not the right approach for several reasons.

I have added a comment on the bug [1] outlining what I think is the right solution here, however - it is far from a trivial change.

Let me know if the comment on the bug makes sense and if I need to add more information.

I will try to devote some time to fixing this, as I believe this is causing us a lot more problems in the gate on an ongoing basis (see [2] for example), but the discussion in the bug should be enough to get anyone else who may want to pick it up on the right path to making progress!

Best,
N.
