Title:
  Failed deployment of VM due to the use of guestfs.GuestFS
  (close_on_exit = False)

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  After Bug 1261475 was fixed, A new issue in Ice-house was introduced.
  Basically now that ice-house is doing the call guestfs.GuestFS
  (close_on_exit = False), there are different requirements on the
  version of libguestfs.x86_64 and python-libguestfs.x86_64.

  During the deployment of a VM I would get the following error on the
  compute node:

  After doing some research I found out that the close_on_exit parameter
  is supported only on the newer versions of libguestfs.x86_64 and
  python-libguestfs.x86_64.

  In my system (RHEL 6.4) I had
  libguestfs.x86_64 1:1.16.34-2.el6
  python-libguestfs.x86_64 1:1.16.34-2.el6

  After updating to the following versions the deploy operation started working again.
  libguestfs.x86_64 1:1.20.11-2.el6
  python-libguestfs.x86_64 1:1.20.11-2.el6
