This was actually in my todo list. #INIT and #RESET are actually separate pins > on the processor. So, shouldn't we differentiate between the two too by having > (*vcpu_init) and (*vcpu_reset) separate ? I think a bool argument is good enough. QEMU has different functions, and init ends up doing save/reset/restore which is pretty ugly.
