VMware 克隆CentOS后无法启动网卡的解决
#首先要保证udev-post 启动chkconfig --list|grep udev
udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off
service udev-post start
#将原有的eth0那一行注释，然后将生成的eth1改为eth0
vim /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0a:31:75:62:3c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0a:31:75:62:3c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
#最后修改网卡的配置文件
