If you apply the folowing patchset

https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg01552.html,
and [PATCH v2 00/11] cpu: add i386 cpu hot remove support
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg01557.html,
qemu can support hotplug and hot-unplug cpu device.
So this patch series will make libvirt support hotplug and hot-unplug cpu
device for qemu driver, and now only supports one cpu driver which is
'qemu64-x86_64-cpu'.
The cpu device's xml like this:
<cpu driver='qemu64-x86_64-cpu' apic_id='3'>
Do we really need to expose this 'qemu64-x86_64-cpu' string to apps.
It feels like a rather low level QEMU private implementation detail
to me that apps should not need to know or care about. I think libvirt
should always just do the right thing to make cpu hotplug work.
