bringing up interface eth0: error no suitable device found

配置上网:

 

虚拟机克隆的时候出现的问题,会因为复制了网卡信息导致这个情况,具体处理方式如下

 

解决办法:

首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:

复制代码
# 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:29:67:c5:e2", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:75:d1:d7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
复制代码
也就是说,克隆的时候把网卡的MAC地址也克隆了,导致了有两个系统有相同的MAC地址。于是,要么把DEVICE=eth0改成DEVICE=eth1,然后HWADDR改成00:0c:29:75:d1:d7;要么在70-persistent-net.rules文件中把eth0的地址改成00:0c:29:75:d1:d7,同时把eth1的配置注释掉,然后在ifcfg-eth0中修改HWADDR。之后再service network restart即可。

我使用的方法是 注释eth1 把eth1的 ATTR{address}=="00:0c:29:75:d1:d7"粘贴到要使用的“eth0” 中去

然后修改配置文件  cat /etc/sysconfig/network-scripts/ifcfg-eth0 将其中的 HWADDR= 08:00:27:4f:47:15更改为刚才是信息
