Unfortunately, not able to hotplug memory. Is anything changed from your previous posting or I am doing something wrong? After giving value to "requested-size", I see size as zero. (qemu) qom-set vm0 requested-size 10G (qemu) info memory-devices Memory device [virtio-mem]: "vm0" memaddr: 0x240000000 node: 0 requested-size: 10737418240 size: 0 max-size: 107374182400 block-size: 2097152 memdev: /objects/mem0 Guest kernel: 5.6.0-rc4 Using same Qemu commandline arguments mentioned in cover-letter. Thanks, Pankaj
