vmware eth0丢失
右键->设置->网络适配器->移除->添加->高级->Mac地址改成原来的->启动->service network restart

vmware镜像复制时eth0丢失
方法一：我已复制该虚拟机(推荐)
vi /etc/sysconfig/network-scripts/ifcfg-eth0->删除mac地址，改IP->rm -rf /etc/udev/rules.d/70-persistent-net.rules->reboot
方法二：我已移动该虚拟机
vi /etc/sysconfig/network-scripts/ifcfg-eth0->删除mac地址，改IP->service network restart
