Re: [lxc-users] near-live migration
Ah, I see. https://github.com/lxc/lxd/issues/3326 It looks like that's a prerequisite for something like lxc move c1 s-tollana: --stateless on a running container.

Re: [lxc-users] near-live migration
While not a direct answer, I filled an enhancement bug recently for this exact topic (incremental snapshots to remote server). The enhancement was approved, but I don't know when it will be included in the next LXD version.

The 'move' step can take some time. I wonder if it would be easy to implement/do something like: - prepare move (e.g. take snapshot an copy upto snaphot) - stop - copy the rest - remove snapshot on dst - remove container from src - start container on dst That would minimize downtime without the complexity of a live migration. What are your thoughts?

[lxc-users] near-live migration
Hi, Right now I'm using the sequence 'stop - move - start' for migration of containers (live migration fails too often). The 'move' step can take some time. I wonder if it would be easy to implement/do something like: - prepare move (e.g. take snapshot an copy upto snaphot) - stop - copy the rest - remove snapshot on dst - remove container from src - start container on dst That would minimize downtime without the complexity of a live migration.
