OpenNebula 运行虚拟机失败

你好，我正在尝试按照本教程使用 OpenNebula 运行虚拟机： http://docs.opennebula.org/4.8/design_and_installation/quick_starts/qs_centos7_kvm.html

但是当我想要实例化一个模板时，vm 会失败并且日志中显示：

Wed Nov 12 09:48:25 2014 [Z0][LCM][I]: New VM state is PROLOG.

你知道哪里出了问题吗？
谢谢

答案1

错误消息表明您无法使用 ssh 连接到本地主机：

failed: ssh: connect to host localhost port 22: Connection refused

防火墙中 sshd 是否正在运行并且端口 22 是否打开？
