Centos Nic installation failure in hyper-V

Faults:

1,/etc/sysconfig/network-scripts directory no ifcfg-eth0

2. If the ifconfig command does not have eth0, only LO is displayed.

Solution:

1. If you enter ifconfig without eth0:, you need to install the NIC driver as follows:

Check the NIC type and whether the NIC driver is installed in Ubuntu

1 input: lspci or lspci-V orLspci-VV

All hardware information and versions are displayed, and then you can search for drivers in Linux Online.
0:00. 0 Ethernet controller: Broadcom Corporation BCM4401-B0 100base-tx (Rev 02)
. 0 FireWire (IEEE 1394): Ricoh Co Ltd r5c832 IEEE 1394 controller (Rev 05)

Ethernet controller: network card model

My Nic model: Ethernet controller: Intel Corporation device 1502 (Rev 04)

 

Net drive: e1000e-1.6.2.tar.gz, High Version compatible with low version

Install linux IC v3.2.iso in hyper

# Mount/dev/CDROM/Media

#/Media/install. Sh

# Reboot

II,Check whether the NIC Driver exists.

Enter ifconfig-A on the terminal

If only lo link encap appears: local loopback
 

No NIC Driver.

If eth0 link encap: Ethernet hardware address 00: 1c: BF: CA: 14: D7 is returned
 

It indicates that the NIC Driver Installation is correct.

3. Create or copy a ifcfg-eth0 File

Delete RM/etc/udev/rules. d/70-persistent-net.rules

CP ifcfg-Lo ifcfg-eth0

Or create a ifcfg-eth0 File

The content is as follows:

Device = eth0

Onboot = Yes

Type = Ethernet
