failure in OST exits with following error:
scenarios/004_basic_sanity.py", line 500, in <lambda>\n    lambda: api.vms.get(VM1_NAME).status.state == \'down\',\nAttributeError: \'NoneType\' object has no attribute \'status\'\n--------------------- >> end captured logging << ---------------------'


This is a little confusing as to the reason of failure and it would be helpful in future debug if the tests exists with graceful error. 


Further info from ykaul on ovirt list: 


    This is a test error - code like this is always wrong:

        api.vms.get(VM1_NAME).status.state == something

    In this case, api.vms.get() returned None. The test code
    should handle None and fail with meaningfull error, or maybe
    retry the call.


It doesn't matter - if api.vms.get(VM1_NAME) return None, we'll fail the test. So we can add an assert here, but still fail in exactly the same manner. 
Gracefully with 'VM1_NAME was not found' ? Perhaps.
