Title:
  test_live_migration_* tests fail with fakelibvirt

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  With the recent merging of https://review.openstack.org/73428,
  test_live_migration_(changes_listen_addresses|raises_exception)
  requires fakelibvirt to have the migrateToURI2() method (if libvirt,
  at least v0.9.2, is not installed) so that it can be mocked out by
  those tests, otherwise the following mox errors occur during unit
  testing.

  UnknownMethodCallError: Method called is not a member of the object:
  migrateToURI2

  patch attached (which i may submit properly in the next 24 hours if
  someone doesn't beat me to it),  with signature taken from upstream
  libvirt and mocking stolen from fakelibvirt's migrateToURI().

  full error log:
