Hi, As you may know, currently QEMU supports several features that help live migrations to operate more predictively. These features are: auto-converge and post-copy. I made a research on performance characteristics of these two features, you can find it by the following link: https://rk4n.github.io/2016/08/10/qemu-post-copy-and-auto-converge-features/ <https://rk4n.github.io/2016/08/10/qemu-post-copy-and-auto-converge-features/> Hope you find it helpful.
