Why using hypercall_page ?
Hello,
I am studing Xen hypercall now. I found that hypercall is invoked via

page fault in shadow page-table
Hi,
I am reading shadow memory code in Xen 3.3.0, and have a question.
In HVM guest, if a process writes a non-existing page, what happens:
First, page fault occurs, and traps into Xen. Xen finds out that that page doesn''t exist in guest page table, so go back to guest.
The guest fixes this fault in its page table, and writes that page again. Because that page doesn''t exist in
