Subject: Page Fault in PV?
Date: Mon, 5 Mar 2012 14:54:39 +0800 [thread overview]
Message-ID: <CAF2sySM6Vf23+aJ9Je_iTzB8zs5GAPwRWfAegqywyVoFMseMYA@mail.gmail.com> (raw)
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?
