## xNVMe를 통해 ZNS 생성
![xNVMe](https://github.com/OpenMPDK/xNVMe)는 NVMe device를 위한 크로스 플랫폼 라이브러리입니다.
리눅스 환경에서 아래 순서로 커맨드를 입력하시면 ZNS SSD를 생성하고 테스트해볼 수 있습니다.
테스트 결과는 html 파일로 생성됩니다.

이 내용은 [링크](https://github.com/OpenMPDK/xNVMe/runs/1065843776?check_suite_focus=true)
내용을 기반으로 합니다.

``` bash
docker network prune --force --filter "label=xNVMe-net"
docker network create --label xNVMe-net xNVMe-net
docker pull refenv/qemu-nvme:latest
docker create --name xnvme-test --label xnvme --workdir /__w/xNVMe/xNVMe --network xNVMe-net --privileged -e "HOME=/github/home" -e GITHUB_ACTIONS=true -e CI=true -v \

```

아래 내용은 `docker exec -it xnvme-test bash`를 하여 도커 프로세스의 bash에서
작성하는 내용에 해당합니다.
