 SSH tunneling ain't set up between the compute nodes.
 Got in nova.log the following error:
  ProcessExecutionError: Unexpected error while running command.
  Stderr: u Host key verification failed.\r\n

Steps to reproduce:
 Run #openstack server migrate ...
 or NovaServers.boot_and_migrate_server rally scenario

    Support nova non-live migration

    Ensure that each compute node is configured with ssh key

Reset to "confirmed" since in case with ceilometer on board the nova user shell is being modified by scripts of ceilometer-common package.
