K8s doesn't support orchestrating LXC/LXD containers as far as I know. What I did was to use LXD containers as hosts/nodes for K8s. So, it was basically application containers/pods and K8s running inside system containers.

In addition, there are orchestrators which can run LXC containers (LXD is a management layer over LXC). Hashicorp Nomad is noteworthy.

Added later: K8s runs OCI containers. All OCI containers I have seen are application containers. I don't know if OCI specification supports system containers.

I still don't see the technical difference, and lxc/lxd doesn't seem to provide one.
