I think this is overkill.

The old code wants cmdResult to be exactly 0.  But guess what - if
you pass NULL to virRun, then virRun errors out unless the exit
status is exactly 0.

That is it is better to just do:

rc = virRun(argv, NULL);

and delete the rest of this attempt at warning about non-zero
status, as virRun does a better job of it in the first place.
