    ``CONF.validation.run_validation`` default enabled.
    This option required to be set ``true`` in order to run api tests
    stability when the guest cooperation required. For example when
    the guest needs react on Volume/Interface detach.
    The ssh test makes sure the VM is alive and ready
    when the detach needs to happen.
    The option was enabled on the gate for a long time.
