  I tried to write a file inside xen during hypercall or do_page_fault,but I find out that I can not use linux kernel code to acomplish this.After searching in the xen's source code,I find  not clue of xen itself using any file operation,which confuse me.So i want to ask how to write/read a file inside xen,and how xen swap out a page or xen just give the Guest OS the privilege to write directly to disk.
