問題：用Vmware克隆Centos 6.4後，發現系統內只有eth1,而且/etc/sysconfig/network-scripts/下只有，ifcfg-eth0文件，雖然可以上網，但無法設置靜態IP。
ifconfig eth0
eth1: error fetching interface information: Device not found
解決：vi /etc/udev/rules.d/70-persistent-net.rules 顯示爲：
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:48:85:9c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
將 NAME="eth1" 改成NAME="eth0"
並將 ATTR{address}=="00:0c:29:48:85:9c",中的網卡地址改到
/etc/sysconfig/network-scripts/ifcfg-eth0 文件中，HWADDR="00:0C:29:48:85:9C"，使他們對應。
然後reboot
ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:48:85:9C
inet addr:192.168.74.148 Bcast:192.168.74.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe48:859c/64 Scope:Link

完成。
