Oh sorry, actually I have not so strong desire on cpu hotplug but I have on memory hotplug and just want to learn stuffs to implement it from cpu's one.

Could I ask you what's the difference between the two implementations? Don't we have a possibility to have different implementations in qemu-kvm (and SeaBIOS)? And also I want to ask that the problem can be applied to memory hotplug case?
