CentOS linux resolves device eth0 does not seem to be present

One, the problem description

CentOS Linux cloned in VMware.

Ifconfig ... Didn't see eth0. Then reboot the NIC and report the following error.

Failure phenomenon:

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]

Ii. the solution

First, open the/etc/udev/rules.d/70-persistent-net.rules content as shown in the following example:

# Vi/etc/udev/rules.d/70-persistent-net.rules

# This file is 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 your keep each of a single

# line, with 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 "

Record the MAC address of the ETH1 network card 00:0c:29:50:bd:17

Next, open/etc/sysconfig/network-scripts/ifcfg-eth0

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

Change the device= "eth0" into Device= "eth1",

Change the hwaddr= "00:0c:29:8f:89:97" to the MAC address above hwaddr= "00:0c:29:50:bd:17"

Finally, restart the network

# Service Network Restart

Or

#/etc/init.d/network Restart

It's normal.

2;

Remove the/etc/udev/rules.d/70-persistent-net.rules file and reboot the system.

3;

If the above doesn't work

(1), ifconfig View the value of the HWADDR

(2) Modifying the HWADDR value detected in the ifconfig in the/etc/sysconfig/network-script/ifcfg-eth1;
