Hi Adam, thanks for your efforts, for me such an API would be very helpful. I tried to use it by applying this patch http://git.kernel.org/?p=linux/kernel/git/rusty/linux-2.6-for-linus.git;a=patch;h=7e280facc1c0ab91e20dbc93d8e8dd88ca6ebaad against vanilla 2.6.32.2 and using latest libvirt from git, but when I do $ virsh dommemstat mydomain I just get an empty line of output, no error message, nothing. Ballooning works fine, but as I said, no statistics output. I'm also using virtio for net and blk - did I miss something (additional entry in the dom-config?) or is there something going wrong? I'm using qemu-kvm-0.11.0 currently, -0.12 is not working for me. Could that be the cause?
