解决Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.

一、问题描述

OS:centos

原因是拷贝虚拟机造成的。

使用vmworkstation打开虚拟机的时候,要选择copy而非move。

二、解决描述

网络上解决步骤各异,其实就一句话。只要保证vmwrare virtual machine.vmx配置文件ifconfig –a/etc/sysconfig/network-scripts/ifcfg-eth0 /etc/udev/rules.d/70-persistent-net.rules所使用的网卡设备和MAC地址一致即可

三、具体操作

1) 确认vmx配置文件的mac地址

ethernet0.generatedAddress = "00:0c:29:f3:fe:4b"

2) ifconfig –a 确认当前网卡和mac地址

[root@Grace Desktop]# ifconfig -a

eth1 Link encap:Ethernet HWaddr 00:0C:29:F3:FE:4B

BROADCAST MULTICAST MTU:1500 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

Interrupt:19 Base address:0x2024

lo Link encap:Local Loopback

………………………………

3) 重命名/etc/sysconfig/network-scripts/ifcfg-eth0为ifcfg-eth0

[root@Grace Desktop]# cd /etc/sysconfig/network-scripts

[root@Grace network-scripts]# mv ifcfg-eth0 ifcfg-eth1

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

DEVICE="eth1"

BOOTPROTO="dhcp"

HWADDR="00:0C:29:F3:FE:4B"

…………

4) 修改vim /etc/udev/rules.d/70-persistent-net.rules

注释掉eth0的记录,打开eth1的记录

vim /etc/udev/rules.d/70-persistent-net.rules

# PCI device 0x1022:0x2000 (vmxnet) (custom name provided by external tool)

#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0C:29:F3:FE:4B", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1022:0x2000 (vmxnet)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:f3:fe:4b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

5) 重启网络服务

会读取刚才修改过的配置文件,如果配置文件不生效的话,使用source命令使得配置文件生效即可。

service network restart
