Device eth0 does not seem to be present,

    用Oracle VirtualBox 安装 CentOS 6.0 后，网络连接不上 service network restart 出现以下提示

      evice eth0 does not seem to be present

使用ifconfig 命令只能看到lo  的状态信息，  使用ifconfig -a   如下

   eth0变eth4了，晕，想了半天，明白了，是因为我装linux后，把linux虚拟盘复制了4次，以满足我的多系统的测试。 所以复制后的网卡分别变成1-4了。

    我是这样解决的，

先把脚本eth0 改成 eth4

[root@linux ~]# mv  /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth4 

[root@linux ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth4

DEVICE="eth4"

//绑定网卡mac地址
HWADDR="00:0C:29:75:9D:A8"  #(注意，这是原来eth0的MAC 要改成ifconfig -a 后显示的 eth4的MAC哦）

NM_CONTROLLED="yes"
ONBOOT="yes"
BROADCAST="192.168.1.255"
BOOTPROTO="static"
IPADDR="192.168.1.133"
NETMASK="255.255.255.0"
NETWORK="192.168.1.0"
GATEWAY="192.168.1.1"

 

      保存后

service network restart 解决问题
