VMware虚拟机克隆Linux系统引起的网卡问题
1. 手动配置静态网卡地址不生效
2. 网卡名变成了eth1
[root@localhost network-scripts]# ls |grep ifcfg
ifcfg-eth0
ifcfg-lo
[root@localhost network-scripts]# ifconfig
eth1 Link encap:Ethernet HWaddr 00:0C:29:3A:8B:02

[root@localhost network-scripts]# vim ifcfg-eth0
DEVICE=eth0

手动设置静态ip地址和网关后，保存退出；然后重启网络后出现错误
[root@localhost network-scripts]# service network restart
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]
[root@localhost network-scripts]#
英汉互译
No suitable device found: no device found for connection ‘System eth0’.
没有找到合适的设备：没有找到设备连接的系统eth0”。
总结了以下解决方案
更改ifconfig显示的eth1网卡名为eth0，并设置static ip地址
编辑/etc/udev/rules.d/70-persistent-net.rules文件，把NAME=”eth0″的那行配置注释掉或者删掉，把NAME=”eth1″的修改成NAME=”eth0″，修改后如下：
[root@localhost network-scripts]# 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 0x8086:0x100f (e1000)
#SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”00:0c:29:52:39:18″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”00:0c:29:3a:8b:02″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
查看以下信息
[root@localhost network-scripts]# ls |grep ifcfg-
ifcfg-eth0

[root@localhost network-scripts]# vim ifcfg-eth0

重启启动网卡服务
