I've been testing what place would be the best to have the emulator send a event and it turns out the hvmemul_acquire_page is not ok. What worked form me was having the emulator send write access violations from hvmemul_map_linear_addr(). Here I can get the gfn, gla and offset for the event. For the exec access violation I've tried to send events from hvmemul_insn_fetch() but there is a problem to get the same variables for the event. Is there a way to go around and get those params for the event? Any thoughts are appreciated.
