Actually, you should get more stats when using the virtio balloon driver in your guests. I use the balloon but I can't get more stats. I use python binding for libvirt and as far as I can see it calls virDomainMemoryStats exactly.
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). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
