I understand. That's why I didn't want to put it in the kvm package to
begin with.

I understand the usefulness of the information.

Right.

No doubt. Again, that's why I didn't want it in the kvm package to begin
with.

Kees' script (IIUIC) is meant to tell users if they have important
security features in their CPU, but for some reason have them turned
off. It's something they're expected to act upon. Just like "Hey,
you've got security updates" is something they're supposed to act upon,
and when acted upon, the notice disappears.

"Yup, you still have VT support" is only vaguely actionable and does not
go away in response to any action you take. I think it makes much more
sense in util-linux.
