Hi,
We are about to upgrade nova to kilo using cells and we noticed
the resize/migrate functionality is not working properly.
The instance is correctly resized/migrated but fails to
“confirm resize” with the following trace:

I can't reproduce in master so this must have been fixed meanwhile,
however I can't identify the patch.
Is someone experiencing the same problem? and know the commit that
fixed it?
thanks,
Belmiro

I'm not seeing anything very different in that specific utility code
path in liberty or mitaka, so I'd have to assume there is something
going on in the online flavor migration when lazy-loading the flavor
from the instance object such that the old or new flavor is None.
Are you rolling to kilo 2015.1.0 or the latest release 2015.1.2?
Are there any debug log messages before the error/trace where it says
it's lazy-loading the flavor and doing anything there? If you know the
instance in question, you could check the instance_system_metadata and
instance_extra tables to see if the old/new flavor information has been
migrated successfully.
I don't think you'd have this problem in master because the online
flavor migration was dropped in liberty (there is a DB migration that
stops you from continuing if you haven't manually migrated the flavors yet).
