This seems to be this BUG():

        static void set_aliased_prot(void *v, pgprot_t prot)
        {
               [...]
        
                if (HYPERVISOR_update_va_mapping((unsigned long)v, pte, 0))
                        BUG();
        
I would expect some log on the hypervisor console (xm dmesg) which
corresponds with this hypercall failure, which would be very useful to
see..

Ian.
