Thank you for your reply. Before this patch, we needed to manually online memory blocks inside the guest, after dimm memory hotplug for most *nix OSes. (Windows guests automatically get their memory blocks online after hotplugging) That is to say, we need to LOGICALLY hotplug memory after PHYSICAL hotplug. This patch did the LOGICAL part. With this patch, we don't need to get into the guest to manually online them anymore, which is even impossible for most host administrators.
As i remember this online step easy can be automate via udev rules.
Logically that's true, but adding udev rules means: 1 you have to get into the guest 2 you have to be familar with udev rules. Not convenient enough compared to just calling libvirt API to do so. -- Oscar oscar.zhangbo@huawei.com
