[Qemu-devel] [PATCH 0/8] [PATCH RFC v3] s390 cpu hotplug

[Jason J. Herne]

From: "Jason J. Herne" <address@hidden>

Latest code for cpu Hotplug on S390 architecture.   This one is vastly simpler
than v2 as we have decided to avoid the command line specification 
of -device s390-cpu.

The last version can be found here:
http://lists.gnu.org/archive/html/qemu-devel/2013-06/msg01183.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.
