Everything I saw on the screen was in the e-mail. After the failure it
hangs for a moment then it resets (in spite of being passed noreboot).

The domain builder just passes the error up to the caller:
<snip>
ctxt->cpu_ctxt.esi = VADDR(KPTDI, startinfopa); /* start info mapped
address */
ctxt->cpu_ctxt.eax = PTOM(IdlePTD);
ctxt->cpu_ctxt.ebx = PTOM(KPTphys);
ctxt->cpu_ctxt.edi = physindex;
if (finish_mmu_updates(xc_handle, mmu))
goto error_out;
/* index of first free physical page */
return physindex;
error_out:
return -1;
}
