在VMware里克隆出来的CentOSLinux。。

ifconfig...没有看到eth0.。然后重启网卡又报下面错误。
故障现象：
servicenetworkrestart
Shuttingdownloopbackinsterface:[OK]
Bringinguploopbackinsterface:[OK]
Bringingupinterfaceeth0:Deviceeth0doesnotseemtobepresent,delayinginitialization.[FAILED]

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
#Thisfilewasautomaticallygeneratedbythe/lib/udev/write_net_rules
#program,runbythepersistent-net-generator.rulesrulesfile.
#
#Youcanmodifyit,aslongasyoukeepeachruleonasingle
#line,andchangeonlythevalueoftheNAME=key.
#PCIdevice0x1022:0x2000(pcnet32)
SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:8f:89:9
7",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0"
#PCIdevice0x1022:0x2000(pcnet32)
SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:50:bd:1
7",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="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
#servicenetworkrestart
或者
#/etc/init.d/networkrestart
正常了。
