1. did XSM hooks are placed in the source code of xen manually?
As we all know, the hooks are used to insert authorization checks on the security-critical operation, now my question is, 
2. how to identify security-critical operation?
security-critical operations are inter-VM communication and cooperation implementing on top of shared virtual resources,
3. does the XSM hooks cover all the operations completely?
thanks.
