OK, now we know where the difference understanding comes from.
But I have different opnion here:
Qemu monitor reset --> do_system_reset ->
qemu_system_reset_request -> reset_requested = 1;
Above ops happens in non-vcpu thread, but this thread doesn't do
real reset ops. It is the VCPU thread which will do
qemu_system_reset if reset_requested == 1 later on.
Maybe I still miss your point :-(
