Title:
  Hyper-V: Captured image size is 0

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  If the original image A size is 123456, then deploy an instance B
  based on the image A. Next capture an image C based on the instance B.
  As a result, the size of image C will be 0.

  After investigation, I think the root cause is the meta data is never
  updated  during snapshot. See this:
  https://github.com/openstack/nova/blob/master/nova/virt/hyperv/snapshotops.py#L45
