Live migration of containers via the CRIU featureset (checkpoint+restore in userspace, which is now part of the mainline Linux kernel) is also an interesting theoretical possibility - AIUI the Kubernetes folks are at least thinking about supporting it. (Live migration fits remarkably well with containers since it requires comprehensive namespacing of all system resources - abstracting away from any dependence on the local machine - which is also how containerization works to begin with.)
