With Zhi trying to run Xen 3.3.0, he won't be using native support
in any operating system. Is there any reason it would really matter whether
or not there is native dom0 support for the kernel included with the OS once
one compiles their own Xen and xen-kernel anyway? I would offer
troubleshooting suggestions, but I have no experience with nat on Xen.

hey!
please note, that fedora 9 doesn't have native support for running F9 as
Dom0. i use centos 5.2 as dom0. it doesn't have support for the newest
hardware but it works very stable. if you want to use Fedora, please use
Fedora 8 (!) as Dom0, as it has native support for Dom0.
greets,

Betreff: [Xen-users] NAT with static ip configuration doesn't work
Hi, All
I have a very basic configuration as this:
Dom0 is based on Fedora core 9. Xen 3.3.0 built from source code. Dom0 is a
standard build of 2.6.18.8-xen.
I have only one physical NIC connected to the Internet. The DomU is a ubuntu
server 8.04 HVM. I did the
following steps to setup NAT network for my domU.
1. change /etc/xen/xend-config.sxp to use NAT:
(network-script network-nat)
(vif-script vif-nat)
2. the configuration file for domU is as
vif = [ 'mac=00:16:xx:xx:xx:xx, ip=10.0.0.1']
When I create the domU, the scripts will bring up two extra interfaces:
vif3.0 and tap3.0.
That is, now I have four interface: eth0, lo, vif3.0 and tap3.0. Eth0 is
connecting to the Internet.
Everything looks ok, but I can't ping the domU from dom0. Neither can I ping
the dom0
form domU.
>From a quick tcpdump, it seems that the virtual NIC in domU is actually
connected to
Tap3.0. Nothing shows up in vif3.0. If I bring down vif3.0 and configure the
tap3.0 with
the router address, everything works just fine.
I am just wondering if I have done anything wrong. Supposedly the official
release of XEN
should be able to work under such a simple configuration. Thanks
Best regards,
Zhi
