 Error: Connection activation failed: Device not managed by NetworkManager
scenario:安装好rhel6后,reboot后,
 service network restart, 有此错误弹出
解决方法:
  /etc/init.d/NetworkManager stop
  chkconfig NetworkManager off
  chkconfig network on
  service network restart
其实上面就是将NetworkManager服务停止,并设置成开机不随系统启动,然后设置network服务开机随系统启动! 重启network服务!
原因:
you have problem because both of NetworkManager and Network using same Network driver and default network blocking access for NetworkManager. if you disable NetworkManager your problem will disappeared after restart
 
 

或:

#setup

       把系统服务 NetworkManager 取消随系统自动启动,只保留network服务随系统启动,因为若NetworkManager和network同时启用的话会产生冲突.

#reboot  设置后重启启动系统
