Live migrating vitual machines is an interesting ongoing area for virtualization: guests keep getting bigger (more vcpus, more vram), and demands on the uptime for guests keep getting stricter (so no long pauses between a VM migrating from one host to another).

This session will go through the simple design from the early days of QEMU/KVM live migration, how it has been tweaked to where it is now, and where we're going in the future. It will discuss how live migration actually works, the constraints within which it all has to work, and how the design keeps needing new thought to cover the latest requirements.

The discussion will cover known unknowns, i.e TODO items, for interested people to step up.
