It takes 'ram_size' as VM's real RAM size which is wrong after we hotplug memory. This bug exists since we begin to support hotplug memory, and it is better to fix it. Patch 3 add some trace events, it helps debugging balloon. If it is unnecessary, pls feel free to remove it. Thanks, zhanghailiang v2: - fix compiling break for other targets that don't support pc-dimm zhanghailiang (3): pc-dimm: add a function to calculate VM's current RAM size virtio-balloon: Fix balloon not working correctly when hotplug memory virtio-balloon: Add some trace events hw/mem/pc-dimm.c | 26 ++++++++++++++++++++++++++ hw/virtio/virtio-balloon.c | 21 +++++++++++++++------ include/exec/cpu-common.h | 1 + stubs/qmp_pc_dimm_device_list.c | 5 +++++ trace-events | 4 ++++ 5 files changed, 51 insertions(+), 6 deletions(-) -- 1.7.12.4
