我尝试在ubuntu 12.04上安装openstack essex，在完成所有进程后，我的nova-network运行不正常。
当我检查/var/log/nova-network.log上的错误消息时，我收到如下错误消息：
Exit code: 2
Stdout: ''
Stderr: "Bad argument `SNAT'\nError occurred at line: 23\nTry `iptables-restore -h' or 'iptables-restore --help' for more information.\n"

这是什么意思？
我该怎么做才能解决这个问题？

答案 0 :(得分：0)
这似乎是一个令人讨厌的错误，现在下一步行动将解决问题：
[root @ server nova] #vim /etc/nova/nova.conf
添加：
fixed_range = 10.11.0.0/24 #####（无论您的网络是什么，都不要添加评论）
服务openstack-nova-network restart 停止openstack-nova-network：[FAILED] 启动openstack-nova-network：[确定]

希望这有帮助。
