  From the DT binding point of view, it would be fine. Conceptually it
would also be fine. However, I doubt that the current libxl

I can't see why it would not work. I think we designed the refcount for
this purpose.

libxl doesn't see the actual mappings, does it ?  It just puts things
into the p2m.

Yes. That's why I think multiple mappings is actually possible.
