Hi All,

Ubuntu had this "Network Manager" component which messed up things with XEN for me in the past. Could you please remove the network-manager network-manager-gnome packages and try again to give the interface an IP address using the /etc/network/interfaces file?

sudo apt-get remove network-manager network-manager-gnome

Emre

This was the first thing I tried, but that doesn't change things for me. I did
it via "up ethtool -K eth0 tx off" in /etc/network/interfaces...

Thanks anyway!
