This feels like we've let the plugin API get slightly more access to QEMU's internals than is ideal. Whether an area of memory happens to be an IO memory region or a memory-backed one (or whether a device is implemented with one region or three, or what names we happened to assign them) is kind of a QEMU internal implementation detail. thanks -- PMM
