This reads as if the hypervisor was imposing a limit here, but looking at xen_get_max_pages(), xen_foreach_remap_area(), and xen_count_remap_pages() I take it that it's a restriction enforced by the Xen subsystem in Linux. Furthermore from the cover letter I imply that the observed issue was on a Dom0, yet xen_get_max_pages()'s use of XENMEM_maximum_reservation wouldn't impose any limit there at all (without use of the hypervisor option "dom0_mem=max:..."), would it?
