Re: [libvirt] [PATCHv2.5 00/10] Add support for memory hotplug

Hi Peter, While playing around with memory hotplug implementation, I found that the guest XML isnt updated after a successful hotplug operation : [root@kop2 test-libvirt]# ./bin/virsh attach-device rhel71-be /home/prerna/mem-hp.xml Device attached successfully [root@kop2 test-libvirt]# ./bin/virsh qemu-monitor-command rhel71-be --hmp "info memdev" memory backend: 0 size: 1073741824 merge: true dump: true prealloc: false policy: default host nodes: [root@kop2 test-libvirt]# ./bin/virsh edit rhel71-be < Does not reflect an updated memory value or a separate dimm device >

I have observed this on PowerKVM. Wondering what is a good place to observe the hot-added memory : Should this reflect as an updated value for current memory in domain XML, or should this show up as a memory device of type: <memory model='dimm'> <source> <pagesize unit='KiB'>4096</pagesize> <nodemask>1-3</nodemask> </source> <target> <size unit='KiB'>524287</size> <node>1</node> </target> </memory> I would be happy to work on a patch to fix this. Pls provide me your thoughts.
