克隆虚拟机启动网卡提示错误 Device eth0 does not seem to be present, delaying initialization...

错误原因：

克隆的Linux系统在新的机器上运行，新服务器网卡物理地址已经改变。而/etc/udev/rules.d/70-persistent-net.rules这个文件确定了网卡和MAC地址的信息之间的绑定，克隆后的网卡的MAC已经发生了变化，所以导致系统认为网络设备不存在，网络不能正常启动。另外一个就是/etc/sysconfig/network-scripts/ifcfg-eth0里面MAC地址也是以前的旧信息。

关于/etc/udev/rules.d/70-persistent-net.rules这个文件，系统在启动时会自动监测变化，然后由/lib/udev/write_net_rules写入到/etc/udev/rules.d/70-persistent-net.rules中一个新的配置节，网卡的的序号依次递增（如原来为eth0,则修改第一后生成一个eth1,再次修改后生成一个eth2...）,且其ATTR{address}的值为当前网卡对应的mac地址。

解决方法：

1、找到/etc/udev/rules.d/70-persistent-net.rules 记录eth1的mac地址，删除该文件。

2、编辑/etc/sysconfig/network-scripts/ifcfg-eth0配置文件，将ifcfg-eth0的配置文件里里面以前的关于MAC地址这一行删除掉或修改为1中的MAC。

另外克隆的服务器的IP设置的是静态IP，克隆完成后BOOTPROTO 可能变成 dhcp，重新修改为static，然后修改IP地址。

3、重启机器，系统会自动生成一个70-persistent-net.rules文件，一切恢复正常。
