在VMware里克隆出来的CentOS Linux。。

ifconfig...没有看到eth0.。然后重启网卡又报下面错误。

故障现象：

service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]

CentOS Linux解决Device eth0 does not seem to be present_present

二，解决办法

首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：
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, aslong asyou keep eachrule 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

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


将 DEVICE="eth0"改成 DEVICE="eth1",
将 HWADDR="xx:xx:xx:xx:xx:xx"改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"


最后，重启网络

service network restart或者/etc/init.d/network restart


正常了。

、删除/etc/udev/rules.d/70-persistent-net.rules文件，重启系统。

、如果上面的不起作用
(1), ifconfig 查看HWADDR的值
(2), /etc/sysconfig/network-script/ifcfg-eth1中修改ifconfig中查出的HWADDR值；
