I followed the first page of the "Installing Xen On An Ubuntu 8.04 (Hardy Heron) Server From The Ubuntu Repositories" HOWTO but after rebooting my host system does not have a network connection. (I have not created a guest system yet) I followed all the steps, even installed the new kernel package (from tokyo) twice. I now have peth0, eth0 and lo. eth0 was dhcp initially and I thought that might be the issue but after setting it up static there is change. Have rebooted several times to no avail. Removed dhcp3-client, no joy. I checked the /etc/udev/rules... to make sure the correct NIC was being selected. I checked lsmod to make sure the 'igb' (Supermicro serverboard) NIC module was loaded. Even unloaded and reloaded it. No joy with anything. Rebooted and selected initial "-server" non-xen kernel and I have networking. (as per static device config) Any help would be appreciated. Thanks.
