We've had a discussion with (iirc) George and perhaps a few others
about "guest" vs "domain", and I've learned that generally the
former is meant to exclude Dom0 while the latter would include it.
In that light either s/guest/domain/ for the help text, or please add
explicit mention of Dom0 there (as PV is still the prevailing kind of
Dom0, and you wouldn't want to trip people into disabling this just
because they only run HVM guests).
