RHEL6.3解決Device eth0 does not seem to be present

如下內容轉載於：http://www.linuxidc.com/Linux/2012-12/76248.htm

一：打開/etc/udev/rules.d/70-persistent-net.rules內容以下面例子所示：

# 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:89:97", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1022:0x2000 (pcnet32)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:17", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

二：記錄下，eth1網卡的mac地址00:0c:29:50:bd:17

三：編輯/etc/sysconfig/network-scripts/ifcfg-eth0

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

將 DEVICE="eth0"  改爲  DEVICE="eth1"  ,

將 HWADDR="00:0c:29:8f:89:97" 改爲上面的mac地址  HWADDR="00:0c:29:50:bd:17"

四：重啓網卡和網絡服務

/sbin/ifdown eth0

/sbin/ifup eth0

service network restart
