VMware 克隆CentOS 后无法启动网卡的解决

VMware 克隆CentOS 后无法启动网卡的解决方法心得笔记。

首先要保证udev-post 启动

[root@localhost ~]# chkconfig –list|grep udev

udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off

[root@localhost ~]# /etc/init.d/udev-post start

Retrigger failed udev events [ OK ]

[root@localhost ~]#

将原有的eth0的那一行注释掉，然后将生成的eth1改为eth0

[root@localhost ~]# cat /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 0x8086:0x100f (e1000) #SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?“, ATTR{address}==”00:0c:29:8c:61:3e”, ATTR{type}==”1”, KERNEL==”eth“, NAME=”eth0” # PCI device 0x8086:0x100f (e1000)

SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?“, ATTR{address}==”00:0c:29:3c:e6:09”, ATTR{type}==”1”, KERNEL==”eth“, NAME=”eth0”

[root@localhost ~]#

最后修改网卡的配置文件,将HWADDR的值修改为/etc/udev/rules.d/70-persistent-net.rules文件中的新值

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

TYPE=Ethernet

UUID=fb802c67-087a-4f50-812b-f3d20053aa4b

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=none

HWADDR=00:0C:62:3C:E6:09

IPADDR=192.168.100.212

PREFIX=24

GATEWAY=192.168.100.1

DNS1=192.168.100.1

DEFROUTE=yes

IPV4_FAILURE_FATAL=yes

IPV6INIT=no

NAME=”System eth0”

[root@localhost ~]#

最后重新启动系统

reboot
