本文介绍如何在Xen虚拟环境中配置Dom0，并通过修改相关设置实现虚拟机网络从桥接模式转换为NAT模式的过程。主要内容包括：Dom0配置文件的调整、虚拟机配置文件的修改、虚拟机的重启及网络状态检查。

配置：
1. Dom0里修改/etc/xen/xend-conf.sxp文件，把原有bridge相关设置注释掉，使用nat设置：

vi /etc/xen/xend-config.sxp
(network-script network-nat)
#(network-script network-bridge)
#(network-script network-route)
(vif-script vif-nat)
#(vif-script vif-bridge)
#(vif-script vif-route)

重启xen
/etc/init.d/xend restart

2、停止虚拟机
#xm shutdown appdata_vm

修改虚拟机配置文件/etc/xen/appdata_vm

name = "appdata_vm"
uuid = "5f82d3e7-8962-bd78-2652-3804c30cafb7"
maxmem = 6114
memory = 6114
vcpus = 8
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
disk = [ "tap:aio:/data/appdata_vm,xvda,w","tap:aio:/data/appdata_vm.img,xvdb,w" ]
#vif = [ "mac=00:16:36:60:56:30,bridge=peth1,script=vif-bridge" ]
vif = [ "mac=00:16:36:60:56:30,ip=192.168.0.6" ]
dhcp = "off"
启动虚拟机
#xm create appdata_vm
3、查看
#ifconfig
