Is this a DomU or a Dom0 kernel?

>From my scant understanding the following is true:-

only Dom0 gets to see the true hardware still runs above the hypervisor

If frambuffer mode requires direct access to hardware then it may not work.
I am not positive but does frambuffer involves direct writing to video
memory

DomU gets to see idealized Xen hardware and presumably uses some sort of Xen
video driver.

DomU does no direct rendering to screen instead it uses VNC

I may however be so so wrong as I am a bit new to this
