Got following issue:
kata-ctl direct-volume add /kubelet/kata-direct-vol-002/directvol002
"{\"device\": \"/home/t4/teawater/coco/t.img\", \"volume-type\":
\"directvol\", \"fstype\": \"\", \"metadata\":"{}", \"options\": []}"
subsystem: kata-ctl_main
 Dec 30 09:43:41.150 ERRO Os {
    code: 2,
    kind: NotFound,
    message: "No such file or directory",
}
The reason is KATA_DIRECT_VOLUME_ROOT_PATH is not exist.
