 Hi:
    I wanna write code about sharing memory between dom0 and domU, and I de=
cide to use void *xc_map_foreign_range(int xc_handle, unint32_t dom, int si=
ze, int port, unsigned long mfn) (this is a function in xenctl.h).
   My question is :
   If I wanna map a range of memory in dom0 to domU, how can I=A1=A1get the=
 value of mfn? and I do not know the port here.

   Can anybody help me ?
   Thanks .
