Yes, my mistake, and this points us straight at the problem.

You see the xc_domain_memory_populate_physmap() call at the end of
libxc/xc_dom_x86.c:arch_setup_meminit()? That needs to be put in a for loop,
allocating no more than, say, a million pages at a time.

The patch should be very simple, so I'll leave the rest to you.
