xen_contig_mem is called correctly, and page ownerships are set to be dom0.
However, the mmu-update that goes wrong attempts to do a MMUEXT_SET_FOREIGNDOM
to a domain with number 32753, and that fails because the owner is 0. Who is
in domain 32753, and why does dom0 wish to map these pages to a foreign domain?
