And with non-massive mem (so the guest actually boots up), the guest does show only 40 bits of phys mem addressing, so qemu will definitely have to increase that to be able to provide >1TB of phys mem to the guest (assuming qemu doesn't adjust that dynamically based on the total mem provided to the guest)
