Hi Paolo and Sean,
It is clear to me now. Thanks much for your reply and help.

Hi Sean,
Thanks much for your detailed replies. It's clear to me why GPAs are
different from HVAs in QEM/KVM. Thanks! I appreciate it if you could
help with the following two more questions.

BTW, I assume the software logic for KVM to find the HPA with a given HVA
(as you said like below) should be the same as the hardware logic in MMU
to translate ``GPA -> [extended/nested page tables] -> HPA''. If this is
true, I cannot understand how KVM can find a correct HPA with an HVA (e.g.,

Hi Sean,
Thanks for the prompt reply. Please see my following reply. Thanks.

Hi QEMU/KVM developers,
I am sorry if my email disturbs you. I did an experiment and found the
guest physical addresses (GPAs) are not the same as the corresponding
host virtual addresses (HVAs). I am curious about why; I think they
should be the same. I am very appreciated if you can give some
