Does vbox has this feature or in the road-map? If not, someone is familiar with the code base can show me some lights on what's the start point to add this feature?
What do you mean with "compress" - identifying indentical pages between VMs and eliminating the duplicates? That's been added in VBox 3.2, page fusion.
True compression of memory pages doesn't sound sensible to me at the VM level - we don't know as much about the meaning/use pattern of a memory page than the guest OS. Compressing the wrong pages would potentially do more harm than good. It's a feature which is popping up in some operating systems, and there it makes sense.
