I seem to know what happened to me. Now I pass throught 00.12.{0,1,2} and
there's no problem now. But if I plug in my keyboard and mouse, then
because of the USB controller is passed to the VM, then I have no keyboard
or mouse to use, so the system seems to hang.However, I still don't know why there exists some kernel oops in previous tests.
