[PATCH kernel v8 0/4] Extend virtio-balloon for fast (de)inflating & fast live migration
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

[PATCH v7 kernel 0/5] Extend virtio-balloon for fast (de)inflating & fast live migration
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
