Respective checking is supposed to by done by (only) Xen in our case. I thought we do so, hence if there's a bug in there I think it wants fixing on the Xen side. The Dom0 kernel should never be exposed the Boot Services areas, and hence it should really trust Xen having done whatever needs doing. Jan
