[root@mhxy171 ~]# 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'.

解决方式：
1、修改ifcfg-eth0中的hwaddr值，
2、删除/etc/udev/rules.d/70-persistent-net.rules 文件
3、重启服务后
