With the way things are currently if the in-guest tool calls set_mem_access for an altp2m view, it implies it wants to receive #VE for it. Wouldn't this change in this patch effectively make it impossible for an in-guest tool to decide which pages it wants to receive #VE for? The new HVMOP you are introducing is only accessible from a privileged domain..
