non, ça ne marche pas vraiment. D'ailleurs, la doc est explicite sur ce sujet : "Live migration means migrating an instance while it is running. This method is supported for virtual machines. For containers, there is limited support. ... For containers, there is limited support for live migration using CRIU. However, because of extensive kernel dependencies, only very basic containers (non-systemd containers without a network device) can be migrated reliably. In most real-world scenarios, you should stop the container, move it over and then start it again. If you want to use live migration for containers, you must first make sure that CRIU is installed on both systems. To optimize the memory transfer for a container, set the migration.incremental.memory property to true to make use of the pre-copy features in CRIU. With this configuration, Incus instructs CRIU to perform a series of memory dumps for the container. After each dump, Incus sends the memory dump to the specified remote. In an ideal scenario, each memory dump will decrease the delta to the previous memory dump, thereby increasing the percentage of memory that is already synced. When the percentage of synced memory is equal to or greater than the threshold specified via migration.incremental.memory.goal, or the maximum number of allowed iterations specified via migration.incremental.memory.iterations is reached, Incus instructs CRIU to perform a final memory dump and transfers it." > > Franchement je me demande comment cela est possible.
