Ah I just answered this on the Xen list without realising you were
using Debian.

I can recommend running debootstrap in dom0 to download the minimal
configuration.  Then you edit a few of the config files there, and
tar it up to use as a template for future guests.

If you use the same filesystems then you will only need one kernel
that can beused for all of them; if some have special kernel needs
then maybe they can be done as modules.

Setting up something like an apt-proxy is useful since after you've
booted with the template install you will want to apt-get a few
things that are not necessarily needed in every guest.  For example,
any guest that I am going to be spending a fair amount of time
editing files in I will want to install vim, but for those where I
don't edit much I will leave it with vi.

Here is a page of some of my experiences:
