虚拟机迁移或克隆后centos 5.8 6.4 网卡不能启动问题解决办法
事先需要查看虚拟机的MAC
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:29:08:52:5f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x8086:0x100f (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:2d:55:3e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3" /etc/sysconfig/network-scripts/ifcfg-eth cat /etc/sysconfig/network-scripts/ifcfg-eth3 DEVICE=eth3 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=192.168.99.201 NETMASK=255.255.255.0 GATEWAY=10.0.0.254 DNS1=10.0.0.254 IPV6INIT=no USERCTL=no HWADDR=00:50:56:2d:55:3e
centos5.8系统下涉及文件(红色字体需要更改)
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) DEVICE=eth1 BOOTPROTO=none ONBOOT=yes HWADDR=00:0c:29:ed:2d:8e NETMASK=255.255.255.0 IPADDR=192.168.99.200 GATEWAY=10.0.0.214 TYPE=Ethernet
另外如果5.8系统下有/etc/udev/rules.d/70-persistent-net.rules 直接删除.
全部修改完毕后
/etc/init.d/network restart 直接重启
