在VMware下,克隆了一个虚拟机,打开克隆后的虚拟机,发现网卡标识符从eth0开始
[root@localhost ~]# ifconfig

打开udev文件
[root@localhost ~]# vim /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:29:81:7a:b1", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:81:7a:a7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:81:7a:a7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
删除里面的网卡配置,重启系统,即可恢复正常
[root@localhost ~]# vim /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.
[root@localhost ~]# reboot
重启后,网卡配置恢复正常
[root@localhost ~]# ifconfig
