Description of problem: qemu-kvm-rhev-2.1.2-1 couldn't support memory hot-plug with command: (qemu)object_add memory-backend-ram,id=mem1,size=1G (qemu)device_add pc-dimm,id=dimm1,memdev=mem1 then get error message as follows: 'DIMM property node has value 0' which exceeds the number of numa nodes: 0 Device 'pc-dimm' could not be initialized But it is successful inside qemu-kvm-rhev-2.1.0-4 Version-Release number of selected component (if applicable): inside host: rpm -qa|grep qemu qemu-kvm-rhev-2.1.2-1.el7.x86_64 uname -r 3.10.0-184.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.boot qemu with command: /usr/libexec/qemu-kvm -name RHEL-Server-7.0-64 -m 4G,slots=4,maxmem=8G -smp 4,cores=2,threads=2,sockets=1,maxcpus=160 -monitor stdio 2.do memory hot-plug inside qemu: (qemu)object_add memory-backend-ram,id=mem1,size=1G (qemu)device_add pc-dimm,id=dimm1,memdev=mem1 Actual results: wouldn't do memory hot-plug and get error message like this: 'DIMM property node has value 0' which exceeds the number of numa nodes: 0 Device 'pc-dimm' could not be initialized Expected results: do memory hot-plug successfully and there is no error message Additional info:
