I hadn't followed the virCommandSetDryRun() discussion. I certainly was
uncomfortable with adding the load/unload tests since yes, the host
would be affected, but I still wanted a way to be able to ensure that
they worked in a "controlled environment". The other hurdle with using
the new API is the downstream changes requiring yet another API...
