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.
