As a side note, I'll raise that I am not a particular fan of the "droppable" terminology, at least with the "read 0s" approach. From a user perspective, the memory might suddenly lose its state and read as 0s just like volatile memory when it loses power. "dropping pages" sounds more like an implementation detail.Long story short: it's the hypervisor that could be effectively dropping/zeroing out that memory, not the guest VM. "NONVOLATILE" might be clearer than "DROPPABLE".
Surely you mean "VOLATILE", not "NONVOLATILE", right? Jason
