目前宿主系统ubuntu 8.04 server可以正常使用网络，但虚拟机下的Guest OS Win2k Server无法访问网络，Ping不通任何IP，浏览器也无法打开网页，在Win2k的网络设置里试过自动获取IP或指定IP：192.168.122.1，都不行，请求高人指点，我目前的情况该如何设置虚拟机和Win2k的网络？

服务器：Xeon 5420，机器在机房，IDC给分配的IP为：211.99.195.***
宿主系统：ubuntu 8.04 server 64bit
虚拟机：qemu-kvm
Guest OS：windows 2000 advance server

我在“管理”菜单中的“全局设定”如下图设定：

再在客户机“设置”中这样设定桥接：

于是我就能ping通了，也能上网了。
希望能帮到你，不过我的问题还是没有人帮我。

谢谢楼上的兄弟！

我的问题搞定了，win2k 这么设置就能连通网络了：
IP：192.168.122.2
网关： 192.168.122.1
子网掩码：255.255.255.0
DNS：192.168.122.1
