David Hildenbrand authoredWhile we fence unplug requests from the outside, the VM can still trigger unplug of virtio based memory devices, for example, in Linux doing on a virtio-mem-pci device: # echo 0 > /sys/bus/pci/slots/3/power While doing that is not really expected to work without harming the guest OS (e.g., removing a virtio-mem device while it still provides memory), let's make sure that we properly handle it on the QEMU side. We'll add support for unplugging of virtio-mem devices in some configurations next. Message-ID: <20230711153445.514112-5-david@redhat.com> Tested-by:
