We should mention somewhere that it's best to shut down the labs before powering off the server, and described the cleanup procedure.

Could consider to set https://containerlab.dev/manual/nodes/#auto-remove on VMs

That just sets the '--rm' flag. It won't clean up Docker networks or other artifacts like clab_files or other directories containerlab creates. The only way to do a proper cleanup is to run 'netlab down --cleanup'

It also prevents setting the restart policy for Linux containers: https://github.com/srl-labs/containerlab/blob/main/runtime/docker/docker.go#L506

But you are right - it doesn't cleanup everything
