Title:
  nova-compute shouldn't spawn two libguestfs appliances every time an
  instance is launched

Status in OpenStack Compute (nova):
  Expired

Bug description:
  https://bugzilla.redhat.com/show_bug.cgi?id=1064947

  Using RHELOSP 4.0 GA bits, I'm finding that when I launch the Cirros
  0.3.1 image, separate calls to libguestfs within the nova codebase
  cause qemu-kvm to be run twice *before* the instance is launched.
  This is suboptimal.

  One libguestfs call (file injection) can be disabled by setting
  libvirt_inject_partition=-2, but this does not work for the second one
  (checking to see if the volume partition/filesystem can be extended).
  The codepath for the second call is approximately:

  /nova/virt/disk/api.py extend()
  /nova/virt/disk/api.py is_image_partitionless()
  /nova/virt/disk/vfs/guestfs.py VFSGuestFS.setup()

  It would be good if all of this could be done with one libguestfs
  instance which could also be disabled in the global nova config.
