Title:
  min_count ignored for instance create

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  Fix Released

Bug description:
  The server create API takes min_count and max_count values for the
  number of instances to  be created, where the actual number to be
  created should be the highest value allowed by quota between these
  limits.

  However the code in compute/api.py does a single check against
  max_count and then treats the exeception as a failure - resulting in
  messages such as:

  min_count=1
  max_count= (quota+1)

  "Quota exceeded for instances: Requested 1, but already used 13 of 40
  instances"


  The code in _check_num_instances_quota() looks like it has most of the
  logic for adjusting the values when it gets an OverQuota exception
  from the initial reservation request based on max_count - but always
  ends up raising TooManyInstances .
