Hi, This series implements an early protoype of a new feature called automatic ballooning. This is based on ideas by Rik van Riel and I also got some help from Rafael Aquini (misconceptions and bugs are all mine, though). The auto-ballooning feature automatically performs balloon inflate and deflate based on host and guest memory pressure. This can help to avoid swapping or worse in both, host and guest. This series implements the guest part. Full details on the design and implementation can be found in patch 2/2. To test this you will also need the host part, which can be found here (please, never mind the repo name): git://repo.or.cz/qemu/qmp-unstable.git balloon/auto-ballooning/rfc Any feedback is appreciated!
