Re: [Xen-devel] HVM Hypercalls

No, noone has done the work yet because it generally suffices to have PV guests mapping foreign memory. Noone who cares to have HVM guests able to map foreign memory has provided code to support it.

Is it because of the migration issues that the grant hypercalls(mapping,copying,….)are not supported?

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

Are the Hypercalls related to Grant tables supported?
