# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface

iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto
auto eth0
auto br0
iface br0 inet static
address 192.168.7.64
netmask 255.255.255.0
gateway 192.168.7.254
bridge_ports eth0

auto eth0.101 

auto br101
iface br101 inet manual
    bridge_ports    eth0.101
    bridge_stp      off
    bridge_maxwait  0
    bridge_fd       0

　　

2、手动在后天把在portal生成的vnet12和vnet13加入这个网桥

brctl addif br101 vnet12
brctl addif br101 vnet13

3、ok
