about "Guest OS crash"

[Frankenstein-bit]

Hi,I find your awesome work. When I look up throug your code,I find something I am very interesting, here is the part I am interesting : /* Explicit page hook function / static int mlearn_set_hook_kernel_text(void) { / XXX: When set hooks to entire kernel area, Guest OS crash. */ return mlearn_set_hook_range (kernel_start_page, kernel_end_page , KVM_PAGE_TRACK_ALL); }

Can you tell me why this situation happen? and how do you solve this problem?
