The hotplug feature in qemu 1.5 uses a new monitor command. The support 
was recently added to libvirt by:

     qemu: Implement new QMP command for cpu hotplug

     This patch implements support for the "cpu-add" QMP command that plugs
     CPUs into a live guest. The "cpu-add" command was introduced in QEMU
     1.5. For the hotplug to work machine type "pc-i440fx-1.5" is required.

The commit will be included in the upcomming 1.1.0 release of libvirt.
