i want to access a page (which is in other guest,such as hvm)in kernel space of domain 0 ,and i can get the gfn of this page. what will i do?
i know in dom0's user space i can use xc_map_foreign_range()(libxc) to map this page to dom0,and then i can access it. but in kernel space,i can not use this function.
