I wonder if it makes sense to consolidate the various balloon approaches into a single driver, and keep the amount of ballooned memory into account when reporting statistics in /proc/meminfo. When you want to introduce some interface in Xen, you probably want something more powerful than these, Xen has a nice balloon driver, that can also be controlled from outside the guest domain. -- "Debugging is twice as hard as writing the code in the first place.
