Let's register the notifier and trigger the qapi event with the right device id. MEMORY_DEVICE_SIZE_CHANGE is similar to BALLOON_CHANGE, however on a memory device level. Don't unregister the notifier (we neither have finalize() nor unrealize() for VirtIOPCIProxy, so it's not that simple to do it) - both devices are expected to vanish at the same time. Cc: "Michael S.
