FYI if min_disk is set properly in the image, it will fail on download.
Glance should be automatically setting min_disk from virtual_size when
it can. Virtual size of qcow images can be determined via qemu-img info
with just the first 512 bytes or so of the image.

** Also affects: glance

Title:
  Flavor's disk is too small for requested image.

Status in OpenStack Image Registry and Delivery Service (Glance):
  New
Status in OpenStack Compute (Nova):
  In Progress

Bug description:
  I uploaded an image to glance and booted it. Once it landed on a
  compute node it tried to download the image to the compute node over
  and over and fails with this exception and never goes to error state.
