Title:
  image status='active' but size=0 after registration

Status in OpenStack Image Registry and Delivery Service (Glance):
  Won't Fix

Bug description:
  version essex

  we use "glance add ... location=http://a_host/an_image"; to register an
  image to glance. if the image store host ("a_host" in this example) is
  unavailable during the registration, then the image is 'active', but
  its size is set to 0 in the database table glance.images.

  this may cause issues when using such images to create VMs (assuming
  "a_host" in the above example is available during the processing of
  this VM creation command). note that if the size of the image is 0 in
  DB glance.images, then one can create a VM with an image whose real
  size surpasses the max-allowed size of a flavor (the image size
  checking related to the "root_gb" constraint imposed by the flavor
  parameter is effectively bypassed in this case).

  should nova check this case and avoid using images whose size is 0 to
  create VMs? or should the size of images be set to some other value in
  this case to indicate the exceptional situation (i.e., the
  unavailability of the image store host)?
