Set KVM (Virtual Machine) to access the Internet through the bridge in rhel5.4

Log on to the system as root and create a bridge configuration file

# Cd/etc/sysconfig/network-scripts/

# Cp ifcfg-eth0 ifcfg-br0

# Vi ifcfg-br0

An example of a bridge script configuration file is as follows:

Device = br0

Bootproto = none

Onboot = Yes

Ipaddr = 192.168.0.10

Netmask = 255.255.255.0

Gateway = 192.168.0.1

Type = Bridge

Peerdns = Yes

Modify the NIC configuration file

An example of the NIC configuration file is as follows:

Device = eth0

Bootproto = none

Hwaddr = 00: 50: 8d: B7: Cf: 9d

Ipv6init = Yes

Ipv6_autoconf = Yes

Onboot = Yes

Dhcp_hostname = ora.haoqi.cn

Ipaddr = 192.168.0.10

Netmask = 255.255.255.0

Gateway = 192.168.0.1

Type = Ethernet

Peerdns = Yes

Userctl = No

Bridge = br0

Mtu= 9000
