OK, let's allow overlapping, but make it explicit: void cpu_register_memory_region_overlap(MemoryRegion *mr, target_phys_addr_t addr, int priority); We need that ordering, so we need an interface. Regions registered via cpu_register_memory_region must not overlap with existing one or we will throw an hwerror. And they shall get a low default priority. Jan
