From: "Jason J. Herne" <address@hidden>
Latest code for cpu Hotplug on S390 architecture.
The last version can be found here:
http://lists.gnu.org/archive/html/qemu-devel/2013-08/msg00076.html
There is also a patch in this series to add cpu-add to the Qemu monitor
interface.
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 unplugging is currently not implemented by this code.
