Take over this work from Liang. This patch series implements two optimizations: 1) transfer pages in chuncks between the guest and host; 1) transfer the guest unused pages to the host so that they can be skipped to migrate in live migration. Please check patch 0003 for more details about optimization 1). For an idle guest with 8GB RAM, optimization 2) can help shorten the total live migration
