I'm not sure what "simulation" means. Could you tell me how/what do you expect memory hotplug simulation exactly? Memory hot-add code is included in kernel. And, remove(unplug) code has developed (and hopefully, it will be merged to -mm after some cleanups, I think.) I would like to make sure what is necessary. Thanks. -- Yasunori Goto
