But it is. That information is specific to the guest OS, I believe
there's no way of retrieving it without actually connecting to the guest
(via a specialized agent or SSH or whatever). And we're talking about
only Unix/Linux; e.g. Windows provides a different method to retrieve
its memory usage.
So you're right, this is very dependent on the guest OS and I guess
there's no way of doing it in a way that works for every guest.
