打开interfaces 配置文件
vi /etc/network/interfaces将pent0 的dhcp 修改为 static，并添加IP，掩码，网关和DNS
# The primary network interface
iface eth0 inet manual
auto pnet0
#iface pnet0 inet dhcp
iface pnet0 inet static
pre-up ip link set dev eth0 up
bridge_ports eth0
bridge_stp off
address 192.168.163.3
netmask 255.255.255.0
gateway 192.168.163.2
dns-nameserver 192.168.163.2
然后重新 network
/etc/init.d/networking restart
