My VM expertise has hit its limit.  I'm trying to change
pagetable_init() in linux-2.4.26-xenU/arch/xen/mm/init.c
to make room for future allocations of new pages from xen. 
The domain dies as soon as it tries to do this set_pmd()
        set_pmd(pmd, __pmd(_KERNPG_TABLE + __pa(pte_base)));
for any space beyond start_info.nr_pages

The values of pte_base and pmd line up with the values for all the other
ptes, and fall within the "Page tables" region of the domain memory

Does domain creation somehow freeze the page table size for a domain?
