    virt: allow for direct mounting of LocalBlockImages
    
    Block backed images, are already presented as block devices, so
    LocalBlockImages can be mounted directly instead of being linked
    with loopback or nbd to another block device.

Title:
  LVM backed images unnecessarily mounted to block devices

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  When using the libvirt drivers support for LVM backed images, the the
  LVM device is mounted to either a loopback or nbd device before
  finally being mounted to the rootfs directory for the instance. This
  is unnecessary because the image is already exposed as a block drive
  by LVM/device mapper. Thus, the LVM device can be mounted directly to
  the rootfs of the instance.
