We obviously can't say to users "Are you running Windows and are you running PV drivers >= X.Y, if so set lever A to position B, otherwise if you are running some other OS or an earlier version of the Windows PV driver set it to position A".Why not? The device can be chosen on a per-VM basis.
Not everyone knows what guest some random user will be running (consider cloud platforms). Expecting an admin to introspect the guest is not a good plan. Having the same set of levers that work at least reasonably with everything is the way to go. -- Alex Bligh
