CentOS linux resolves device eth0 does not seem to be present

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}== "08:00:27:7e:8c:e7″, attr{type}==" 1″, KERNEL== "eth*" , name= "Eth0″
# PCI Device 0x1022:0x2000 (Pcnet32)
subsystem== "NET", action== "Add", drivers== "? *", attr{address}== "08:00:27:30:c2:57″, attr{type}==" 1″, KERNEL== "eth*" , name= "Eth1″

Record the MAC address of the ETH1 network card 08:00:27:30:c2:57

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

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

The device= "Eth0″ into Device=" Eth1″,
Change the hwaddr= "08:00:27:7e:8c:e7″ to the MAC address Hwaddr=" 08:00:27:30:c2:57″

Finally, restart the network

# Service Network Restart
Or

#/etc/init.d/network Restart

It's normal, it's done.
