Bringing up interface eth0: Error: No suitable device found: no device found for connection 'System eth0'.

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：

# 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，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。

如果以上方式不行试试下面的方法

将ifconfig 查到的 HWaddr 00:0C:29:BA:B1:78 替换掉/etc/sysconfig/network-scripts/ifcfg-eth0 中的HWADDR 即可。
