Hello, I am trying to hot plug and hot(un)plug vCPU to a KVM guest. At the fallowing link, I found out we can hotplug vCPUs on the run time with "cpu add" but the hot(un)plug is still in progress. Is there any update on it. Can we use device add/remove for CPUs? http://wiki.qemu.org/Features/CPUHotplug Also, I also find out that we can use virsh (libvirt) to add and remove vCPUs on the fly but I think it is just putting vCPU to sleep or wake up. Is it a good method to change CPU numbers or will it be performance overhead such as does sleeping vCPUs get any time on the host, are those get scheduled?
