1.4-Installing the KVM module Configuration network

Configuring the NIC

cd/etc/sysconfig/network-scripts/

CP Ifcfg-eth0 IFCFG-BR0

Edit eth0 and Br0 separately

ifcfg-eth0 changed to the following:

Device=eth0

hwaddr=00:0c:29:55:a7:0a

Type=ethernet

Uuid=2be47d79-2a68-4b65-a9ce-6a2df93759c6

Onboot=yes

Nm_controlled=yes

bootproto=None

Bridge=br0

ifcfg-br0 changed to the following:

device=br0

# hwaddr=00:0c:29:55:a7:0a

Type=Bridge

# Uuid=2be47d79-2a68-4b65-a9ce-6a2df93759c6

Onboot=yes

Nm_controlled=yes

Bootproto=static

ipaddr=192.168.11.17

netmask=255.255.255.0

gateway=192.168.11.1

dns1=202.106.0.20

Description: My virtual machine is a bridge mode, so set BR0 IP and my real machine the same network segment, including the gateway is also my router's IP, we can be configured according to their own environment, the purpose is to let the virtual machine can surf the Internet.

/etc/init.d/network restart

Check the network card as follows:
