Hi, In my /etc/xen/xend-config.sxp file, I configured to use NAT-network: (network-script ''network-nat netdev=wlan0'') (vif-script vif-nat) In my VM configure file, I added: vif = [''ip=10.0.0.1'' ] My xend service started fine. But when I start my VM (Windows 7), I got following messages: logger: */etc/xen/scripts/vif-bridge*: online type_if=vif XENBUS_PATH=backend/vif/5/0 logger: /etc/xen/scripts/vif-bridge: add type_if=tap XENBUS_PATHlogger: /etc/xen/scripts/vif-bridge: Writing backend/vif/5/0/hotplug-error Could not find bridge device xenbr0 backend/vif/5/0/hotplug-status error to xenstore. logger: /etc/xen/scripts/vif-bridge: Could not find bridge device xenbr0 logger: /etc/xen/scripts/vif-bridge: Writing /local/domain/0/backend/vif/5/0/hotplug-error Could not find bridge device xenbr0 /local/domain/0/backend/vif/5/0/hotplug-status error to xenstore. logger: /etc/xen/scripts/vif-bridge: Could not find bridge device xenbr0 It seems it is trying to use the bridge network, since the xend service is configured to use NAT script, it cannot find the bridge device. How to fix this? -- Regards， David Shen http://about.me/davidshen https://twitter.com/#!/davidshen84 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

err...I followed this guide<http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2>, and it did not mention the ''script'' option. I will give it a try. Thanks.

I have just tried the ''script'' option, it does no work at all.
I am going to take your advice and set up my network bridge myself. But I
do not have much knowledge with bridging. I used KVM before, and you need
to set up KVM network by manual. This is how I set up a NAT network for my
KVM vm:
tunctl -u user
ip link set promisc on dev tap0
ip addr add 10.0.0.1/24 dev tap0
ip link set up dev tap0
kvm -net nic,macaddr=*mac* -net tap,ifname=tap0,script=no,downscript=no
/path/to/kvm.img
KVM uses TAP, instead Xen uses bridge. Can you be kind to help me translate
above script so it works with Xen?
Thank you.

Yes, I read. Except I do not use Ubuntu, but Gentoo. Anyway, I figured it out myself. Thanks. On Sunday, April 15, 2012, Fajar A.
