Public bug reported:
In compute.api.API._create_instance() we have a min_count that is
optionally passed in by the end user as part of the boot request.
We calculate max_net_count based on networking constraints.
Currently we error out if max_net_count is zero, but we don't check it
against min_count. If the end user specifies a min_count that is
greater than the calculated max_net_count the resulting error isn't
very useful.
We know that min_count is guaranteed to be at least 1, so we can replace
the existing test against zero with one against min_count. Doing this
gives a much more reasonable error message:
controller-0:~$ nova boot --image myimage --flavor simple --min-count 2
--max-count 3 test
ERROR (Forbidden): Maximum number of ports exceeded (HTTP 403) (Request-ID:
req-f7ff28bf-5708-4cbf-a634-2e9686afd970)
