最近在CentOS7中经常碰到虚拟机连不上网的问题，错误代码如下。
Restarting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
[失败]
使用systemctl status network.service命令查看结果如下：
network.service - LSB: Bring up/down networking
Loaded: loaded (/etc/rc.d/init.d/network)
Active: failed (Result: exit-code) since 三 2016-08-17 11:34:36 CST; 54s ago

网络上的办法行不通，如： CentOS7 Failed to start LSB: Bring up/down解决方法也行不通。
最后解决的办法就是将dhcp服务器重启一下，步骤如图所示：
- 保证虚拟机在关机的状态下；
- 点击编辑按钮选择虚拟网络编辑器；
- 点击更改设置按钮；
- 点击还原默认设置。
