I've done some investigating into using the device_add hmp/qmp command to support hot-plugging cpus on S390. The alternative suggestion was to simply use a new cpu_add hmp/qmp command. device_add accepts all of the same options as the -device command line parameter takes. This would imply th

Hi all, this is what our approach to CPU hotplug looks like. With respect to Igor's CPU hotplug series, how should we proceed? Should we change the interface to qemu_system_cpu_add_notifier/qemu_system_cpu_hotplug_request/cpu-add etc? Feedback regarding the non-API part is also highly welcome!
