From: "Jason J. Herne" <jjhe...@us.ibm.com> Improvements and modifications to cpu initialization and the qom cpu model were required to implement hotplug.
Hotplugged cpus are created in the configured state and can be used by the guest after the guest onlines the cpu by: "echo 1 > /sys/bus/cpu/devices/cpuN/online" Hot unplug is not currently implemented.
