INFO: No hypervisors were found, therefore no hypervisor data will be listed.


Expected results:

Need to see only one Failure message and not five.

** According to Kieth:
"I am beginning to think that the error message I display there is terrible.  Hindsight being 20/20 coupled with the fact that I now see how people actually use the tool I think that I can do better.  If you write me a BZ on it I'll try to clean it up somehow.  I'm not exactly sure what I'm going to do because there are a *lot* of HTTP error codes and sometimes the same code has multiple meanings.  As such, it isn't really feasible to create a mapping for every possible problem to a remedy string."
