Linux_解決啟動網卡失敗 Device eth0 does not seem to be present

虛擬機克隆 發現service network restart 啟動失敗

故障現象：

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]

解決辦法一：

首先，打開/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：

# 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"

記錄下，eth1網卡的mac地址00:0c:29:50:bd:17

接下來，打開/etc/sysconfig/network-scripts/ifcfg-eth0

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

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

最後，重啟網絡

# service network restart
或者

# /etc/init.d/network restart

正常了。

方法二：

步驟
1、
vi /etc/sysconfig/network-scripts/ifcfg-eth0
ifcfg-eth0的配置文件裏保存了以前的MAC地址，就把這一行刪除掉在重啟網卡


2、
rm -rf /etc/udev/rules.d/70-persistent-net.rules 刪除後重啟機器
