Don't overwrite virRun error messages

Browse Source 
virRun gives pretty useful error output, let's not overwrite it unless there
is a good reason. Some places were providing more information about what
the commands were _attempting_ to do, however that's usually less useful from
a debugging POV than what actually happened.
