Subject: Re: Doubts regarding Shadow Page Table Management in KVM

I think I have cleared the issue regarding the reverse mapping.

I missed the fact, that the write permission is associated with the PTE. 
I thought that it was associated only with the kernel structures 
maintaining the physical page-frame.

But I want to confirm whether a shadowed guest page refers to "the guest 
PT page that has a corresponding shadow PT page. And the corresponding 
shadow PT page is called the shadow of the former.  Am I right ?


Thanks and regards
Sukanto
