Linux_ resolve boot NIC failure Device eth0 does not seem to be present

Linux_ resolve boot NIC failure Device eth0 does not seem to be present

Virtual Machine Clone Discovery service Network restart failed to start

Failure phenomena:

Service Network restart
Shutting down loopback insterface: [OK]
Bringing Up loopback insterface: [OK]
Bringing up interface Eth0:device eth0 does no seem to be present,delaying initialization. [FAILED]

Solution One:

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.
#
# can modify it, as long as you keep each rule to a single
# line, and change is 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 "

Record the MAC address of the eth1 Nic 00:0c:29:50:bd:17

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

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

Change device= "eth0" to 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.

Method Two:

Steps
1.
Vi/etc/sysconfig/network-scripts/ifcfg-eth0
Ifcfg-eth0 the previous MAC address in the configuration file, delete this line to restart the NIC


2.
Rm-rf/etc/udev/rules.d/70-persistent-net.rules Restart the machine after deletion
