Technically, you can use normal memory accesses, so long as software guarantees
the VMCS isn't resident in the VMCS cache and knows the field offsets for the

issue, e.g. tacking on dirty bits through a PV ABI would be trivial.
Yes, you are right. I was referring to the fact that we cant use normal
memory accesses, but is a bit mis-worded.
If you slot in "architectural" it will read nicely, i.e. "VMCB is already an
architectural datastructure in memory".
Yes, this makes sense. Thanks for the suggestion, will reword as you
suggested.
Thanks,
