配置桥接网卡
添加桥接网卡br0，注释掉已有的eth0配置
[[email protected] ~]# vi /etc/network/interfaces
# 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
#auto eth0
#iface eth0 inet dhcp
auto br0
iface br0 inet static
address 192.168.31.10
netmask 255.255.255.0
broadcast 192.168.31.255
gateway 192.168.31.2
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off重启网络后，就可以看到桥接网卡的配置了：

virt-install 的--network选项指定bridge：
