Title:
  libvirt extract snapshot fails if qemu-img >= 0.12.1

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  New

Bug description:
  Running stable/havana tempest against havana 2013.2 nova with this
  test:

  tempest/tempest/api/compute/images/test_images_oneserver.py:test_create_second_image_when_first_image_is_being_saved

  Using the libvirt driver on x86_64 RHEL 6.5 fails with this:

  http://paste.openstack.org/show/50398/

  Essentially: Stderr: "convert: invalid option -- 's'\n"

  This is the code:

  https://github.com/openstack/nova/blob/2013.2/nova/virt/libvirt/utils.py#L549

  Looks like it's not a new change, it's just incompatible with the
  latest qemu-img:

  https://github.com/openstack/nova/commit/b216ed51914986087ea7dee57bc29904fda001a0

  Looks like in the latest qemu-img the snapshot was moved into it's own
  sub-command:

  [root@rhel62 ~]# qemu-img --help
  qemu-img version 0.12.1, Copyright (c) 2004-2008 Fabrice Bellard
  usage: qemu-img command [command options]
  QEMU disk image utility

  Command syntax:
    check [-f fmt] filename
    create [-f fmt] [-o options] filename [size]
    commit [-f fmt] [-t cache] filename
    convert [-c] [-p] [-f fmt] [-t cache] [-O output_fmt] [-o options] [-S sparse_size] filename [filename2 [...]] output_filename
    info [-f fmt] filename
    snapshot [-l | -a snapshot | -c snapshot | -d snapshot] filename
    rebase [-f fmt] [-t cache] [-p] [-u] -b backing_file [-F backing_fmt] filename
    resize filename [+ | -]size
