Title:
  test_volume_boot_pattern tempest test failure for glusterfs backend -
  Part 2

Status in Cinder:
  In Progress
Status in OpenStack Compute (Nova):
  New

Bug description:
  This bug is in continuation of
  https://bugs.launchpad.net/cinder/+bug/1441050 (Part 1 of the problem)

  This bug is opened to track the 2nd issue that GlusterFS (and in
  future any FS backed driver that uses hyp assisted snapshot) is
  hitting.

  Refer to comment nos: #5 (No. 2) , #6, #8, #10 of
  https://bugs.launchpad.net/cinder/+bug/1441050 for more details

  In short, the testcase tries to delete the snapshot after the VM is
  OFF, which libvirt yet doesn't support for external snapshots, thus
  the excp seen as below :

  2015-04-08 07:22:44.376 32701 TRACE nova.virt.libvirt.driver File "/usr/local/lib/python2.7/dist-packages/libvirt.py", line 792, in blockRebase

  Some mailing list discussion around this issue is available at:
  http://lists.openstack.org/pipermail/openstack-dev/2015-April/060983.html

  This bug is opened to track this issue to figure whether we wait for
  libvirt support or change Nova-Cinder interactions to better handle
  this scenario ?

  Due to this, the Cinder-GlusterFS CI job (check-tempest-dsvm-full-
  glusterfs-nv) is failing, which was otherwise running successfully for
  several weeks.
