Device eth0 does not seem-be present problem, find a solution to the same problem on the Internet,
A smooth solution to the record:

Ifconfig ... did not see eth0. Then restart the NIC and report the following error.

Failure phenomena:

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]

CentOS Linux Solution device eth0 does not seem to be present

Workaround:


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

# Vim/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}== "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 Nic 08:00:27:30:c2:57

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

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

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

Here you need to use the copy y of vim to paste P

If you are currently in edit mode, you need to press the ESC key and then press the CTRL + V key on your keyboard (the normal state only needs to press CTRL + V), and the word "visual block" appears at the bottom of the edit box.

Use the arrow keys to move the cursor and select the text within the rectangular area.

Press the Y key to copy the selected text.

Use the arrow keys to move the cursor to the location where you want to paste, and then press p to paste.

Finally, restart the network

# Service Network Restart
Or

#/etc/init.d/network Restart

It's okay, it's done.
