This solution is heavily based on Daniel's original approach here, but hopefully a cleaner way to impl: https://lore.kernel.org/r/20230601161347.1803440-11-berra...@redhat.com The difference is we use the switchover-hold flag rather than tuning bw+downtime to guide test convergence, comparing to

Add a new migration parameter switchover-hold which can block src qemu migration from switching over to dest from running. One can set this flag to true so src qemu will keep iterating the VM data, not switching over to dest even if it can. It means now live migration works somehow like COLO; we
