Centos 配置eth0 提示Device does not seem to be present（centos7 eth0）
一.故障现象：
delaying initialization
解决：# mv /etc/sysconfig/network-scripts/ifcfg-eth0
sysconfig/network-scripts/ifcfg-eth1
vim
sysconfig/network-scripts/ifcfg-eth1
修改DEVICE="eth0"
为DEVICE="eth1"
然后重启启动网卡尝试下
故障前的操作：
DELL刀片装的是CentOS6.3的操作系统，网卡识别的是em1和em2，由于工作需要做了槽位调整，并启动了刀片
故障现象：
启动后网络不通，通过iDRAC登录后route查看缺省路由正常；
重启网络服务：
[[email protected] ~]# service network restart Shutting down loopback insterface: [ OK ] Bringing up loopback insterface: [ OK ] Bringing up interface em1: Device em1 does not seem to be present,delaying initialization. [Failed]
分析问题和解决：
之前在别的文章中我们提过70-persistent-net.rules文件，所以看了一下：
[[email protected] ~]# 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 0x14e4:0x163a (bnx2) SUBSYstem=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="24:b6:fd:ab:76:1e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x14e4:0x163a (bnx2) SUBSYstem=="net", ATTR{address}=="24:b6:fd:ab:76:1c", NAME="eth0"
发现NAME的名称不正确，依次将上述红色字体中的eth0改为em1，eth1改为em2；
*切记：网卡编号由MAC地址大小决定，MAC越小网卡编号越小；
如下：
…………
# PCI device 0x14e4:0x163a (bnx2)
SUBSYstem=="net", NAME="em2"
# PCI device 0x14e4:0x163a (bnx2) SUBSYstem=="net", NAME="em1"
保存退出~！
[[email protected] ~]#reboot
………………
问题解决~！
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization
centos 装好后克隆一份后，开机，发现没有网卡，然后重启了网络服务：service network restart
发现报如下错误：
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization
解决过程：
1） 删除掉 /etc/udev/rules.d/70-persistent-net.rules
2） vi /etc/sysconfig/network-scripts/ifcfg-eth0
* 删除掉mac 项： HWADDR
* 删除UUID
3） 重启，解决
CentOS device eth0 does not seem to be present...
vmlite 虚拟机启动出错，就把这个虚拟机删除掉重新建立，系统虚拟硬盘使用之前的，启动系统后不能上网，通过 ifconfig 查看网卡没启动，遂启动网卡服务，但是出错，就是：device eth0 does not seem to be present, delaying initialization，然后想到是不是 ifcfg-eth0 的配置文件里保存了以前的 MAC 地址，就把这一行删除掉在重启网卡，还是一样的错误，随后网上查了下资料，把 /etc/udev/rules.d/70-persistent-net.rules 删除后重启机器就可以了，因为这个文件绑定了网卡和 mac 地址，所以换了网卡以后 MAC 地址变了，所以不能正常启动，也可以直接编辑这个配置文件把里面的网卡和 mac 地址修改乘对应的，不过这样多麻烦，直接删除重启，它会自动生成个。
1、
vi /etc/sysconfig/network-scripts/ifcfg-eth0
ifcfg-eth0 的配置文件里保存了以前的 MAC 地址，就把这一行删除掉在重启网卡
2、
/etc/udev/rules.d/70-persistent-net.rules 删除后重启机器
因为这个文件绑定了网卡和 mac 地址，所以换了网卡以后 MAC 地址变了，所以不能正常启动，也可以直接编辑这个配置文件把里面的网卡和 mac 地址修改乘对应的，不过这样多麻烦，直接删除重启，它会自动生成个。
或者以下方法：
ifconfig eth1 确定新网卡的 MAC 地址。
nmcli con 确定新网卡的 UUID
vim /etc/udev/rules.d/70-persistent-net.rules
把原 eth0 的相关信息删除，将 eth1 的 name 改为 eth0
cd /etc/sysconfig/network-scripts
vim ifcfg-eth0
HWADDR = 现在的实际 MAC
UUID = 现在的实际 UUID
上述处理操作完后，重启虚拟机！
CentOS Linux解决Device eth0 does not seem to be present
在VMware里克隆出来的CentOS Linux。。
ifconfig...没有看到eth0.。然后重启网卡又报下面错误。
故障现象：
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]
解决办法：
首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：
# 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"
记录下，eth1网卡的mac地址00:0c:29:50:bd:17
接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最后，重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了。
CentOS Linux解决Device eth0 does not seem to be present!
vi /etc/udev/rules.d/70-persistent-net.rules
1、删除原先的mac地址，然后将下面eth1 修改eth0，然后记录其mac地址,vi /etc/sysconfig/network-scripts/ifcfg-eth0 将HWADDR=为记录的网卡地址。
2、vi /etc/sysconfig/network-scripts/ifcfg-eth0
将其mac地址改为70-persistent-net.rules的eth1的mac地址，然后网卡名改成eth1，reboot重启。
