@garethTheRed의 제안에 따라 다음을 입력했습니다.

이 명령에 대한 결과가 없습니다. 구체적으로 어떤 사항을 변경해야 합니까? 파티션을 추가해야 합니까 disk_test.img? 그렇다면 어떻게 해야 할까요?

이는 /home/disk_test.img파티션 /dev/mapper/centos-home, 즉 호스트의 파티션에 위치합니다. 나는 단지 초보자들이 개선하기 전에 간단히 손에 쥘 수 있는 것을 제공하기 위해 이 책을 내놓았을 뿐입니다.
또한 참고로 사용 가능한 스토리지 풀은 다음과 같습니다.
[root@remote-host ~]# virsh pool-list

다른 파티션 중 하나에 대한 스토리지 풀을 생성한 다음 그 안에 스토리지 볼륨을 생성하고 둘 중 하나를 명령에 전달해야 합니까 virt-install?
