Title:
  nova fails attempting to enumerate libvirt disk images

Status in OpenStack Compute (Nova):
  Confirmed

Bug description:
  Nova (Icehouse) appears to be enumerating all available libvirt
  volumes (at least those in the "default" storage pool) during the
  "Auditing locally available compute resources" process. If these
  images are not readable by Nova it results in the following error:

  2014-11-12 12:02:26.013 3009 ERROR nova.openstack.common.periodic_task [-] Error during ComputeManager.update_available_resource: Unexpected error while running command.
  Command: env LC_ALL=C LANG=C qemu-img info /var/lib/libvirt/images/windows-1.qcow2
  Exit code: 1
  Stdout: u''
  Stderr: u"qemu-img: Could not open '/var/lib/libvirt/images/windows-1.qcow2': Permission denied\n"

  It's not clear to me why Nova is even attempting to run qemu-img on
  these files.  They aren't exposed to or usable by Nova in any useful
  fashion.   The filesystem where these images are stored is not
  utilized by nova for storage.  They seem completely unrelated to
  anything Nova cares about.

  These errors prevent Nova from starting up correctly.
