...esp_data; I think the implementation has an issue here - both the balloon pages and the unused pages use the same buffer ("resp_data" above) to store chunks. It would cause a race in this case: live migration starts while ballooning is also in progress. I plan to use separate buffers for CHUNKS_OF_BALLOON_PAGES and CHUNKS_OF_UNUSED_PAGES. Please let me know if you have a different suggestion. Thanks. Best, Wei

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. Please read each patch commit log for details. Changes: v7->v8: 1) Use only one chunk format, instead of two. 2) re-write the virtio-balloon implementation patch. 3) commit changes 4)
