问题描述：

在VMware里克隆出来的CentOS Linux，开机执行命令：ifconfig…没有看到eth0网卡。然后重启网卡又报以下错误：

Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]

解决办法：

首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面所示：

$ vi /etc/udev/rules.d/70-persistent-net.rules
-# This file was automatically generated by the /lib/udev/write_net_rules
-# program, run by the persistent-net-generator.rules rules file.
#
-# You can modify it, as long as you keep each rule on a single
-# line, and change only the value of the NAME= key.
-# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?”, ATTR{address}==”00:0c:29:8f:89:97”, ATTR{type}==”1”, KERNEL==”eth*”, NAME=”eth0”
-# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?”, ATTR{address}==”00:0c:29:50:bd:17”, ATTR{type}==”1”, KERNEL==”eth*”, NAME=”eth1”

记录下eth1网卡的mac地址00:0c:29:50:bd:17

接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0网卡配置文件

$ vi /etc/sysconfig/network-scripts/ifcfg-eth0

将 DEVICE=”eth0” 改成 DEVICE=”eth1” ,
将 HWADDR=”00:0c:29:8f:89:97” 改成上面的mac地址 HWADDR=”00:0c:29:50:bd:17”

最后，重启网络

$ /etc/init.d/network restart
或
$ service network restart
OK,搞定。
