[openstack-dev] [nova] I think nova behaves poorly when booting multiple instances

I know there were discussions during the summit on how to fix quota bugs, and in particular the multi instance code was making the solution harder.

I agree with you though, if the api is to stay, the current behavior seems broken.

Thanks,
Kevin

Is this causing problems with quotas?  The problem I brought up isn't with
quotas but rather with all the instances being set to an error state when we
could have actually booted up a bunch of them.

In any case, even if we wanted to deprecate it (and I think an argument could be
made for that) we still have to decide what the "correct" behaviour should be
for the API as it exists today.  In my view the current behaviour doesn't match
what a reasonable person would expect given the description of the "min count"
and "max count" parameters.
