Hi,
could you make a ifconfig -a on the Xen-DomainU and send the output please ?
I've read somewhere (can't remember where) a similar problem where
network interface was not started on boot.

Hi,
I am able to boot Xen Domain 0 on Linux 2.6.11.10-Xen0 kernel. The
installation is perfect.
But while booting Xen-DomainU [Linux 2.6.11.10-XenU] I recieve these
messages and after booting into the unprevileged domain, I am unable
to ping Domain 0. The reverse is also not possible.
Running local start scripts.
Starting basic firewall: modprobe: could not parse modules.dep
iptables v1.2.11: can't initialize iptables table `filter': iptables
who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

This is my Domain U configuration.
[root@tux06 xenfs]# cat /etc/xen/tintin
kernel = "/boot/vmlinuz-2.6.11.10-xenU"
memory = 128
name = "tintin"
nics = 1
vif = ['bridge=xen-br0']

disk = ['file:/mnt/xenfs/tintin,hda5,w']

And this is my Domain 0 network configuration:
