Centos虚拟机迁移网卡无法正常启动的解决方法

【问题描述】Centos虚拟机文件直接拷贝到新机器，打开虚拟机后，ifconfig可以正常看到网卡信息并获取IP地址（获取的IP地址不是正确的），执行service network restart，提示以下错误：
network.service - LSB: Bring up/down networking
Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)
Active: failed (Result: exit-code) since Sun 2017-08-27 03:40:23 PDT; 9s ago
Docs: man:systemd-sysv-generator(8)

Process: 5607 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)

【故障原因】网卡配置文件里的MAC地址和新机器获取的网卡地址不一致
【解决方法】修改网卡配置文件里的MAC地址为ifconfig显示的MAC地址。

【PS：克隆虚拟机MAC地址重复的解决办法】

1.网卡配置里#HWADDR先注释掉
2.虚拟机关机
3.Vmware虚拟机设置–网络适配器-高级-生成MAC地址
