Thanks Mikhail. Appreciate the hint. I thought of deleting the flavor,
and add again but was concerned about if that would affect current
instances with that flavor-id in use? Maybe the easiest is to just go
ahead and update the 'nova' table. I just was concerned that there
would be existing relationships that would brake upon e.g. deleting
existing instances, however.. I think I should go ahead and try the
db-update way first. thanks! will
