Hopefully this question belongs in xen-devel and not xen-users:

Is there any kind of inter-domain shared memory facility in Xen?  E.g.
an API callable from DomU user-mode that would cause the system sets
up two DomU's page tables so they a range of virtual addresses in both
resolve to the same set of machine pages?

Thanks,
Dave
