标签：etc key modify 修改 cap drop eth0 使用 back
系统：CentOS 6.9
重启网卡后：service network restart报：
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]；
原因是copy虚拟机造成的。使用vmworkstation打开虚拟机的时候，要选择copy而非move。
1)、确认vmx配置文件的mac地址
2、确定第一步里的MAC地址和下面Mac地址相同时，
vim /etc/udev/rules.d/70-persistent-net.rules，查看ATTR{address}的值是否跟 ifconfig -a 里边 eth1的 HWaddr(物理地址)值相等，执行下面操作
1)、重命名/etc/sysconfig/network-scripts/ifcfg-eth0为ifcfg-eth0
2)、 删除网卡配置文件里不必要的参数
)3、修改vim /etc/udev/rules.d/70-persistent-net.rules（注释eth0 网卡）
4、重启网络服务
ethernet0.generatedAddress = "00:0C:29:57:7F:85" 【在该虚拟机安装文件下】
查看规则文件(vim /etc/udev/rules.d/70-persistent-net.rules)；确定里面的Mac地址和上面第一步存在相同的Mac地址（若不存在相同的Mac地址，则手动创建一个和上面一样的Mac地址）
