All that is completely OS specific, and has no relation to the 
architecture.
As I mentioned in another part of the thread, the closest thing to this
would be to implement SDEI together with an IMPDEF mechanism to enter it
(or even generate a RAS error).

On the other hand, SDEI is pretty horrible, and means either KVM or QEMU
acting like a firmware for the guest. To say that I'm not keen is a 
massive
understatement.
