Hi Thomas, To use the memory statistics API with qemu, you will need support in 3 places: libvirt (you're good here), qemu, and linux. The qemu and linux parts have been accepted but are still staging. If you want to build your own qemu and linux-kernel, let me know and I can provide you some patches.

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=pa...
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?
Thanks for any directions,
kr,tom
