在虚拟机上做实验，克隆虚拟机，并修改IP地址后，重启网络服务出现下面的错误：
[root@hadoop002 Desktop]# service network restart
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Error: No suitable device found: no device found for connection ‘System eth0‘. [FAILED]
处理方法：
1、ifconfig 查看HWaddr地址
2、vi /etc/sysconfig/network-scripts/ifcfg-eth0 修改HWADDR=上面查看的地址
3、service network restart验证成功
Error: No suitable device found: no device found for connection 'System eth0'
