device eth1 does not seem to be present, delaying intitialization 解决办法
最近参与群里的企业级linux综合实验项目的时候，需要大量的虚拟机来搭建实验环境，便使用了一台闲置的8G内存的hp145，安装了esxi4来部署虚拟机，为了方便，安装好一个RHEL6，制作成了OVF模板，添加了两块网卡。结果利用该OVF模板建立新的虚拟机后，网卡无法使用，ifconfig 只有lo的信息，没有添加的两个网卡的ip信息。经过一番查看，终于找到了原因，及相关的解决办法，记录如下：
具体错误信息，
/etc/init.d/network 后会出现
device eth0 does not seem to be present, delaying intitialization
device eth1 does not seem to be present, delaying intitialization
dmesg | grep eth
发现了如下内容
renamed network interface eth0 to eth2
renamed network interface eth1 to eth3
ls /etc/sysconfig/network-scripts/
发现只有
ifcfg-eth0 ifcfg-eth1 的配置文件
而且检查了eth0的配置文件 如下
DEVICE=”eth0″
NM_CONTROLLED=”yes”
ONBOOT=”yes”
BOOTPROTO=static
IPADDR=10.0.8.10
NETMASK=255.255.255.0
并没有任何异常
最后google了一番，出现该问题的时候涉及一个文件
/etc/udev/rules.d/70-persistent-net.rules
具体内容如下：
[root@rhellab ~]# more /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

e”, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth3″
看了这个文件以后，发现了问题的所在。也就想到了解决办法。
只要删掉# PCI device 0×8086:0x100f (e1000) 这四段内容，然后重启即可。
