Title:
  libguestfs: update to use Nova's libvirt URI

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Using OpenStack Nova w/ libvirt on Fedora 18:

  When I boot an instance and inject files (with libguestfs) I get the
  following stack trace in Nova's compute.log file:

  -----

  This issue seems to be that because libguestfs doesn't use the same
  libvirt URI as Nova and thus fails.
