Binary package hint: linux-virtual
I am using Ubuntu Lucid 10.04 inside a Xen 4 domU with the linux-virtual kernel, which is recommended for that purpose. Xen allows for the configuration of the domU's network device(s) via its configuration files in dom0, IP, netmask, hostname etc. can be set there. these settings are then handed over to the kernel of the domU at creation time. On previous installs (with a self-compiled kernel) the domU's eth0 was then brought up automagically with the correct settings, without the need to touch e.g. /etc/network/interfaces on the domU's disk beforehand.
This is a very clean way of keeping the domU's settings together in one file and makes using generic domU images possible (ideally with an upgradeable stock linux-virtual kernel). However, this doesn't work as supposed, since CONFIG_IP_PNP is not set in the linux-virtual kernel configuration. Since the linux-virtual kernel is just there to be used in VMs, I reckon this option should be set anyways in this kernel.
