요딴 에러가 뜬다.

보니까 libvirt가 실행중이 아닌가보다

실재로도 그러하였다.

 

이번에는 이런에러가 났다.

yum install -y guestfs-xfs libguestfs-xfs

이거를 해주자.

우리는 mgmtdb에서 gildong.pem.pub를 manager 인스턴스의 .ssh 아래에 authoirzed_keys로 등록하고 원격지에서 이를 관리하도록 하자.

 

mgmtdb 의 /root/.ssh 디렉토리에서

DB에서

```

ssh-copy-id -i gildong.pem.pub root@211.183.3.128

```
