当Linux bridge agent出现状态问题，且时间同步不是原因时，可能是因为网络接口配置错误。日志显示eno1677提供商接口不存在，实际配置文件中的物理接口映射设置不正确。解决方案是将`linuxbridge_agent.ini`配置文件中的`provider:eno1677`更改为正确的网卡名称。

时间不一样会导致xxx状态，但是时间问题只会出现在compute节点，controller节点或者没有问题的情况下就要考虑其它的了

Interface eno1677 for physical network provider does not exist. Agent terminated!

就是说eno1677网络提供商接口不存在，这个报错就很明显

linuxbridge_agent.ini配置文件下

[linux_bridge]

physical_interface_mappings = provider:这个网卡名字错了找不到

解决方法：改成自己的网卡名字就是
