VMware 克隆虚拟机后网卡无法启动

　　　　今天使用 VMware Workstation 时，出现了一个问题。克隆目前存在的 RHEL 7系统后，网卡无法正常启动，报错如下：

[root@wangmj Desktop]# systemctl restart network
Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.
[root@wangmj Desktop]# systmectl status network.service
bash: systmectl: command not found...
Similar command is: 'systemctl'
[root@wangmj Desktop]# systemctl status network.service 
network.service - LSB: Bring up/down networking

　　　　网上查找解决方案后，发现问题为 配置文件 和  查看到的 MAC 地址不匹配：

进入配置文件修改后网卡成功启动。
