Until the glance issue is addressed, it's not possible to do anything in
nova for this. Removing nova.

** No longer affects: nova

Title:
  No support for sparse images

Status in OpenStack Image Registry and Delivery Service (Glance):
  Confirmed

Bug description:
  I could have sworn I filed this bug already, but I don't see it now.
  Oh, well.

  Glance does not seem to support any sort of sparse images. For
  example, Ubuntu's cloud images are a 1½ GB filesystem, but if it were
  sparsely allocated it would only take up a couple of hundred MB.

  Amazon handles this by using tarballs as their image transport format.
