Hi Daniel,
    Why does your peth0 has an ip-address?

Good question, I don't know... What do you suggest me to do?
Both, eth0 and peth0 have the very same configuration and IP addresses in "ifconfig -a".

irrlicht@home:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Try using static ip instead of dhcp in dom0. Maybe this is messing with your interfaces.

I recently had a networking problem myself, where only pings came through from domU to the physical network. I had to turn off tx checksum offload with ethtool. I integrated it in the xen-network-common.sh script, so maybe this patch will help you too?!

This patch modifies the last line in the "add_to_bridge ()" function:

--- scripts/xen-network-common.sh       2008-05-12 15:22:52.000000000 +0200

Hope it helps,
