For part of my Google Summer of Code work I've put togeather debs for xen of 2.0.7 and of unstable. The unstable debs are built off of yesterdays hg tree, but I try to update them fairly regularly when new developments occur. Currently I only have compiled debs for debian, but the source debs will work on ubuntu also, and I plan on posting compiled files for ubuntu tomorrow. The apt repository is available at http://mirror.clarkson.edu/pub/dists/xenophilia/xendebs/debian available distributions are xen-stable, and xen-unstable. To install a fully working xen system, you only need to install the xen package which depends on all the other needed debs. Please note that these are different from previous available debs, but share many of the same naming schemes etc. Therefore if you are upgrading from a system that used debs from another source, it is recommended that you remove all old packages, and use the --purge option to apt-get in order to clear out any debconf templates.

Differences in these packages from those previously available are primarily apparent in the distribution of kernels. These packages do not distribute a kernel patch (yet) but instead distribute pre-build kernel packages that include debconf scripts to configure the needed grub entries. More information on this system can be found in the man pages for update-grub-xen that are included, and the file /etc/xenkernels.conf. The init scripts are not run by default, but are just installed in /etc/init.d In order to use xm etc, you must start xend manually, or use the update-rc.d script.

If there is interest, these packages could be easy build for x86_64, as long as someone was willing to do the testing, as i do not have a system available.
