Hi, Have you tried the latest qemu (you can git clone from http://git.qemu.org/qemu.git). Actually, i have posted a patch fc50ff0666315be5120c70ad00cd0b0097484b84 pc-dimm: Don't check dimm->node when there is non-NUMA config It should not break memory hotplug feature if there is non-NUMA option. This patch would also allow to use pc-dimm as replacement for initial memory for non-NUMA configs. Note: After this patch, the memory hotplug can work normally for Linux guest OS when there is non-NUMA option and NUMA option. But not support Windows guest OS to hotplug memory with no-NUMA config, actully, it's Windows limitation.

Tsirkin <address@hidden> I think this will fix your problem, it will support hotplug a pc-dimm without configure numa node. Hope this can help you, Thanks Best Regards, zhanghailiang On 2014/10/18 1:11, Mikhail Sennikovskii wrote:
Hi Andrey, thank you for your answer. I know I can work around this by specifying a numa node. My question is though is the current behaviour considered to be a bug, or not. And if yes, when it is expected to get fixed.
