Migrating an LXC container
As of Proxmox VE 5.0, live migration of LXC containers is not possible. The container must be turned off before it can be moved. This is not a limitation of Proxmox but rather the LXC technology itself. To migrate a container, right-click on Container to open the Context menu, and then select Migrate or click on the Migrate button in the top-right corner of the GUI to open the Migration dialog box:
Select a destination node from the Target node drop-down list. Check the Restart Mode box to auto-restart the container after the migration is complete. Click on the Migrate button to initiate the migration. The migration process will auto-stop the container, migrate it to the destination node, and then auto-start it at the end of the process.
Live migration is under heavy development by LXC, so we should expect it in the mainstream LXC package in the near future. To some of us, the lack of this feature may be a huge deal breaker, especially in a container-dominant environment...
