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

RE: [Xen-users] NAT with static ip configuration doesn''t work
Thanks. I think I would just use the quick fix I mentioned in my previous mail for now. But sure it is inconvenient. It is so frustrating to build Xen from source code :(, even the simplest configuration some times doesn''t work.
