Title:
  Resize/Migrate with LVM Restores from Image; Does Not Copy Data

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  It seems when using resize with LVM ephemeral storage simply re-loads
  the base image rather than transferring the LVM data across servers.
  To test simply load an Image and make some file alterations, then
  resize and all changes will be lost. I'm not sure if this is working
  as intended but I'm assuming not; and if not then it is a critical bug
  resulting in 'libvirt_images_type=lvm' being unusable with resize.

  Further testing reveals this happens with Migrations as well leaving
  me to believe this is NOT working as intended and leaves LVM
  critically unusable.
