Per the discussion in gerrit, the zero-byte snapshot is normal from
nova/glance, as it reflects that fact that no space is being taken in
glance, since the volume snapshots are stored in cinder.

** No longer affects: nova

Title:
  Zero-byte image snapshot leads to error launching an instance from
  snapshot

Status in OpenStack Dashboard (Horizon):
  In Progress

Bug description:
  When I try to launch an instance of snapshot image (which was a
  snapshot of a volume-backed instance), the 'launch button' has no
  response.

  How to reproduce:
  1. Launch an instance by using "boot from image(create new volume)"
  2. Take a snapshot of this instance, this operation will produce a image which size is 0 byte.
  3. Launch an instance by using the image generated in step 2, the 'launch button' has no response.

  If I open the console of web browser, I can see the Error Message
   "An invalid form control with name='volume_size' is not focusable. "
