This needs support from qemu and (at least last time I checked) a running guest agent. This isn't available in wheezy so you should see the updated CPUs after reboot only. See. e.g.: http://lost-and-found-narihiro.blogspot.ch/2013/10/fedora-19-kvm-cpu-hotplug-with-qemu.html So libvirt tries to cope with it.
