Hi All,
I want to know if, in the case of HVM (shadow page tables), we can change
the machine frame number pointed to by a page table entry?
An overly simplified example would be: let's say I have page number 10 that
is pointing to machine frame number 10, but I would like it to point to
machine frame number 1? Can this be achieved inside the "sh_page_fault"
function inside "xen/arch/x86/mm/shadow/multi.c" as this seems like a
relevant place for this modification to me.
Thanks!
