How can the guest know? Adding "you can trust physbits" bits somewhere (as suggested by Eduardo) would work for sure, but would depend on a qemu update. Maybe a "don't trust physbits in case it is 40" heuristic works well enough in practice. > Now, regarding the problem "to trust or not" in the guests' physbits, > I think it's an orthogonal discussion to some extent. It isn't. OVMF can't ignore the problem, you risk to break guests if you do. take care, Gerd
