虚拟机是从公司将整个虚拟机文件夹拷贝回家的,在家里的电脑安装了一个vmware8.0
打开虚拟机之后发现网络不能用, 也试了很多方法,包括禁用dns,但是也没有效
最后发现一个方法
在VMware里克隆出来的CentOS Linux。。


ifconfig...没有看到eth0.。然后重启网卡又报下面错误。


故障现象:


service network restart
Shutting down loopback insterface:                                                                                                     [  OK  ]
Bringing up loopback insterface:                                                                                                          [  OK  ]
Bringing up interface eth0:  Device eth0 does not seem to be present,delaying initialization.                    [FAILED]


CentOS Linux解决Device eth0 does not seem to be present


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:


# vi /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 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"


记录下,eth1网卡的mac地址00:0c:29:50:bd:17


接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0


# vi /etc/sysconfig/network-scripts/ifcfg-eth0


将 DEVICE="eth0"  改成  DEVICE="eth1"  ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17"


最后,重启网络


# service network restart
或者


# /etc/init.d/network restart


一切恢复正常了。
