Given the large number of reports we've gotten in the past where poor performance was caused by the expectation that a user had KVM enabled and really didn't, I think it's more important to overcommunicate to the user here. If in the case of libguestfs, you think this isn't something a user should worry about, you can just filter out the message before it hits stderr.
