在VMware的虚拟机中克隆CentOS，在重启网卡的时候报错：

Shutting down loopback  interface : \[ OK \]Bringing up loopback  interface : \[ OK \]Bringing up  interface  eth0: Error: No suitable device found: no device found  for  connection  'System eth0' . \[FAILED\]

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：

![Image 1][]

\# 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"

我们看系统中eth0的配置：

![Image 1][]

\#cat ifcfg-eth0DEVICE=eth0HWADDR= 00 :0C: 29 : 67 :C5:E2TYPE=EthernetUUID=5cb1d564-a7e8-4b57-bdb4-7e76e92f460aONBOOT=yesNM\_CONTROLLED=yesBOOTPROTO=dhcp

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。
