From 722a3c783ef4159b297d86e3c1f345360fb2a362 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 26 Jun 2020 09:22:44 +0200 Subject: virtio-pci: Send qapi events when the virtio-mem size changes 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.
