It allows a domain to give some of its memory back to Xen. This makes its memory footprint smaller. The memory can then be used for other domains. The memory can be reclaimed later so domains can also grow. To use the driver: * In a domain, "cat <memory target> > /proc/xen/balloon" * In domain zero use "xm balloon <dom> <memory target> > Is there doc about it? It's described in the user manual.
