Yes, you're right. NPT is easy but we would have to guess what the spec

Either way, blocking KVM is the easiest thing todo.
How about I fold that into the s/lm_root/pml4_root rename[*]? I.e. make the
blocking of PML5 a functional change, and the rename an opportunistic change?

Yes, that's a good plan. Thanks,
