I see that there are two ways: PV -> emulate_privileged_op(), or hvm handles via handle_mmio()/handle_pio(). I am not familiar with either one, and would help me lot if anybody expert in that can suggest which way hybrid should go, both dom0 and domU. Any suggestions would help. If there are any docs on this, that would be great too. thanks, Mukesh
