Re: [Xen-devel] Measuring the amount of memory read/written (basically touched) by a domU

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

The live migration shadow-pagetable logic could perhaps be used for this.
Live migration uses it for dirty page tracking, but you could extend it no
doubt to both accessed- and dirty-page tracking, and take counts
periodically. Definitely some hacking involved, however!
