VMWare克隆linux系统之后，网卡问题

当linux系统在识别网卡的时候会把mac地址和网卡名称对应起来记录到udev的脚本中，但是VMWare会给我们自动生成虚拟机的mac地址，但是在我们克隆的linux系统中udev脚本中已经记录了原本的mac地址与网卡名称，也就是eth0，但现在克隆过的虚拟机的mac地址已经不再是之前的mac地址了，所以udev就会自动将这个网卡的mac地址对应上网卡eth1（udev会记录所有已经识别的mac地址和网卡的对应关系，网卡名都会+1）kenerl仅仅只识别到了一张网卡，跟网卡名相关的网络配置也就没有发生变化。

解决办法：

1，文件：/etc/udev/rules.d/70-persistent-net.rules

将eth0网卡的代码注释掉，然后将eth1改成eth0

2，修改: /etc/sysconfig/network-scripts/ifcfg-eth0

把mac地址改为新的mac地址，即

HWADDR=00:50:56:bc:00:46

#啰嗦一下 : 更改host名称

编辑 /etc/sysconfig/network
