[Bug 1320754] Re: flavor-recreate-bug
This wishlist bug has been open a year without any activity. I'm going
to move it to "Opinion / Wishlist", which is an easily-obtainable queue
of older requests that have come on.
In case you want to work on that, consider writing a blueprints [1] and
spec [2]. I'll recommend to read [3] if not yet done. The effort to
implement the requested feature is then driven only by the blueprint
(and spec).

Title:
flavor-recreate-bug
Status in OpenStack Compute (nova):
Opinion
Bug description:
I re-created a flavor that is the same 'flavorid' on before and after.
After re-creation, the flavor value of the instance, that created by
the 'flavorid', was changed to the new flavor value.
Currently, the flavor value of the instance is refer to 'flavorid'. In
this case, it should be refer to 'id', not 'flavorid'.
In database scheme, id is really unique but flavorid is perform the
conflict.
