See the hypercall entry points in xen/arch/x86/hvm/hvm.c. Mo= st of the grant hypercalls (the ones that let you map or copy other domains'= pages) are not supported currently.

What are the HVM Hypercalls that are currently supported in Xen-unstable= ?
Are the Hypercalls related to Grant tables supported?
 
Thx,
