Error:Connection activation failed:Device not managed by NetworkManager

運行#/etc/init.d/network restart, 重啓網絡連接時出現以下錯誤：

Bringing up interface eth0: Error:Connection activation failed:Device not managed by NetworkManager

 

在csdn上找到了解決方案，如下：（http://blog.csdn.net/swiftshow/article/details/7367733#）

 

1. Remove Network Manager from startup Services.
#chkconfig NetworkManager off

2. Add Default Net Manager
#chkconfig network on

3.Stop NetworkManager first
#service NetworkManager stop

4.and then start Default Manager
#service network start

 

運行完了命令，還會出現
