You are trying to use the same mem-dev for two different memory regions: * The first 4GB, that's non-hotplug memory living in the first (only) NUMA node (-numa node,memdev=mem-mem0) * Extra hotplugged memory beyond the first non-hotplug 4GB (-object pc-dimm) You can't do that. If you want the guest to have just 4GB non-hotplug memory, simply don't use -object pc-dimm. If you want the guest to have 8GB (4GB non-hotplug and 4GB hotplug), you need two memory backend objects, 4GB each. |
