  • Thread-topic: Seamlessly sharing identical memory pages among domains

I'd like to know if XEN is or will be implementing any mechanism for
transparently sharing pages with identical content among domains, to
minimize memory consumption, similar to what is implemented in VMWare's
ESX server (chapter 4 of the paper whose link is below).

Thanks,
- Roque
