Title:
  image directory naming convention in libvirt driver

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Today libvirt driver in Nova names instance folders according to
  instance name (e.g., "instance-001"), which is not unique. Using the
  uuid of the instance instead will make it much easier to handle
  several scenarios,  including migration (verify availability of the
  instance on the target node), as well as instance rebuild for HA (for
  similar purpose, when shared storage is in place).

  The fix is mainly replacing instance['name'] with instance['uuid'] in a bunch of places in libvirt/driver.py.
  Here is fix propose: https://review.openstack.org/9707
