Hi,

I want to be able to migrate LXC container from one Proxmox node to the next. Right now I am doing backup/restore.

criu supposedly allows for live migration.

Should I hold my breath for Proxmox to provide an interface to migrating container from one node to the next, or would that mean a horrible death for me?

Any and all insight is greatly appreciated.

Within a cluster or standalone Proxmox VE nodes?

In a cluster, you can migrate containers. They will be shutdown and started on the target node.

I haven't been involved, but AFAIK there were attempts to live migrate containers in a cluster with criu, but it wasn't working as (reliably) as we hoped. Not sure about the current state of criu. Others might have more insight.
 
Thanks Aaron, for your quick reply.

At the moment we have two nodes without a (usable) shared storage.

Looking forward to more information that you or your colleagues might be able to provide.
