Which OS are you using in your guests?
Of course, you need to have the virtio balloon driver up and runnig in
your guests.
You also have to have new enough qemu that reports stats without
blocking (qemu 0.14 or newer added stat reporting via qom-get, since the
older query-balloon interface blocks) and libvirt that knows how to read
stats via qom-get (libvirt 1.1.1 or newer).
