kubernetes is not alive after rebooting host

I'm using the latest kuryr-kubernetes deployed with devstack on Ubuntu22.04 VM and k8s works fine. However, it's not running after rebooting the VM.

```
$ kubectl get nodes
The connection to the server 192.168.56.11:6443 was refused - did you specify the right host or port?
```

There is a failure occurred while launching kubelet from systemctl.

```
$ systemctl status kubelet
