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

# 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：

#cat ifcfg-eth0

DEVICE=eth0

HWADDR=00:0C:29:67:C5:E2

TYPE=Ethernet

UUID=5cb1d564-a7e8-4b57-bdb4-7e76e92f460a

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=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。于是解决方法，

A:要么把DEVICE=eth0改成DEVICE=eth1，然后HWADDR改成00:0c:29:75:d1:d7；

B: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。vim /etc/sysconfig/network-scripts/ifcfg-eth0 中的HWADDR ="00:0c:29:75:d1:d7"即可。

之后再service network restart

在使用B方法时，查看IP地址ifconfig 发现还是eth1

eth1      Link encap:Ethernet  HWaddr 00:0c:29:75:d1:d7  
          inet addr:192.168.20.148  Bcast:192.168.20.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe66:3658/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:72 errors:0 dropped:0 overruns:0 frame:0
          TX packets:28 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:7127 (6.9 KiB)  TX bytes:3096 (3.0 KiB)
          Interrupt:19 Base address:0x2024

解决办法：重启虚拟机reboot问题解决 eth1 变成 eth0
