Hi,
        I remove some pages' _PAGE_RW flags and record these pages.
        Then I modify do_page_fault function of Xen. I just add
_PAGE_RW flags to these, when they are written.
        However, my domain still crashes.
        Guest OS are supposed to know nothing about this. Why does this happen?
