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
