Makes sense.

touch "$VAR_SUBSYS_LIBVIRT_GUESTS"

Do we want to detect failures in started (that is, failure to touch the
lock file)?  Then again, failure to touch the lock file merely means
that stop won't be called automatically, but doesn't affect whether we
actually started and can call stop manually, so blindly succeeding seems
okay to me.

rm -f "$VAR_SUBSYS_LIBVIRT_GUESTS"

ACK with those tweaks.
