Just a thought I wanted to throw out but having been running Fedora Core on my AMD64 for awhile now and getting to look at their Xen install I've had a few thoughts. Mostly related to installing domU's. FC has a virt-install that is written in python that's in their python-virtinstall package. It's a nice way to install the domU but it only works currently with a FC install. I've been trying to pick it apart and see if I can't retool it to support installing different domU installs starting with Debian but in theory any. Anyone else tried working on such a beasty and want to combine efforts?
