一、Linux虚拟机克隆后,启动系统发现网卡无法启动,然后ifup eth0网卡会提示(Device eth0 does not seem to be present, delaying initialization.)失败。

 

二、处理方法:

方法一:

1、[root@yum ~]# 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 0×1022:0×2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:7e:8c:e7″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
# PCI device 0×1022:0×2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:30:c2:57″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″

记录下,eth1网卡的mac地址08:00:27:30:c2:57

接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0

 

2、[root@yum ~]#  vim /etc/sysconfig/network-scripts/ifcfg-eth0

将 DEVICE=”eth0″ 改成 DEVICE=”eth1″ ,
将 HWADDR=”08:00:27:7e:8c:e7″ 改成上面的mac地址 HWADDR=”08:00:27:30:c2:57″

 

3、# ifdown eth0 && ifup eth0 或者# /etc/init.d/network restart 或service network restart

方法二:

1、删除(/etc/sysconfig/network-scripts/ifcfg-eth0)网卡MAC地址行(HWADDR=)数据。

2、最后重启操作系统后正常。查看(ifconfig)是否正常。(不推荐该方法)
