Oops, "Host system is Fedora-23, VB-5.1.10 if that matters."

While guest additions often don't have much impact and even older guest
additions verions often work with newer host versions I wouldn't risk
breakage by upgrades of any dependency of the guest or host. Consider
to upgrade the host to 5.1.22, too. Or try using the latest for both.
