This patch series implements two optimizations: 1) transfer pages in chuncks between the guest and host; 2) transfer the guest unused pages to the host so that they can be skipped to migrate in live migration. Changes: v8->v9: 1) Split the two new features, VIRTIO_BALLOON_F_BALLOON_CHUNKS and VIRTIO_BALLOON_F_MISC_VQ, which were mixed together in the previous implementation; 2) Simpler
