1. did XSM hooks are placed in the source code of xen manually? Yes. 2. how to identify security-critical operation? This is why the answer to 1 is yes. It requires reasoning about what different security policies might want to enforce, what might be exploitable or could lead to convert channels, etc. 3. does the XSM hooks cover all the operations completely? Probably not. Certainly not with new features, anyway.
