</pre></blockquote><pre wrap="">virt-manager can graph RAM utilization of guests, so it may be worth
seeing what APIs it used. The virDomainMemoryStats() is probably the
key API to be using, although I'm not sure whether it is wired up in the
xen implementation.

</div><div>Good idea with the virt-manager.

I read something about "xentrace", a tool to read out some CPU counters, which can be used to approximate RAM accesse by using LLC-miss counter.
