libvirt users - Jan 2012 - How to use "virDomainMemoryStats"? I got 0 result.

I use like this;

int n = virDomainMemoryStats(dom, stats, 4, 0);

I want to get men used and not used. If can , I want to get all output in stats.

but "n" result is always 0.


???????????????

That is the correct usage, and the fact that the answer is 0 is a
byproduct of qemu not being able to provide the information.  There are
patches under way so that qemu 1.1 will be able to provide statistics;
but until then, there's nothing libvirt can do if qemu doesn't provide
the information.
