The benefit here is that you can

Hi folks,
I've been updating some old patches which make use of a function to
translate guest virtual addresses into pointers into the guest RAM.
As I understand it qemu has guest virtual and physical addresses, the
latter of which map somehow to host ram addresses.
The function which the code

There were actually two methods described in the thread referred to in the
