在公司机房的物理机上架设 KVM虚拟化的时候,经常需要配置网桥,先要安装网桥工具:

apt-get install bridge-utils   
apt-get install uml-utilities

编辑 /etc/network/interfaces,参考下面配置加入网桥配置信息:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
    address 192.168.10.6
    netmask 255.255.255.0
    network 192.168.10.0
    broadcast 192.168.10.255
    dns-search dell1
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0
    bridge_maxwait 0

auto eth1
iface eth1 inet manual

auto br1
iface br1 inet static
    address 14.152.50.6
    netmask 255.255.255.192
    network 14.152.50.0
    broadcast 14.152.50.63
    gateway 14.152.50.1
    bridge_ports eth1
    bridge_stp off
    bridge_fd 0
    bridge_maxwait 0
    # dns-* options are implemented by the resolvconf package, if installed
    dns-nameservers 114.114.114.114
    dns-search dell1

auto eth2
iface eth2 inet manual

auto br2
iface br2 inet static
    address 112.93.114.2
    netmask 255.255.255.224
    network 112.93.114.0
    broadcast 112.93.114.255
    gateway 112.93.114.1
    bridge_ports eth2
    bridge_stp off
    bridge_maxwait 0
    dns-nameservers 114.114.114.114
    dns-search dell1

上面配置针对双线接入多 IP的情况,这样 br0-br2就可以给虚拟机 guest使用了,br0是内网,br1-br2是电信或者联通出口。
