IIRC debian squeeze is not really the best platform to run xen for
beginners. If you're new to xen, I suggest the archaic-but-just-works

Or even DON'T use xen, use whatever you're familiar with (e.g. kvm,
vmware, whatever).

And depending on what you run on it, using lxc on ubuntu precise might
actually be a better choice as it is VERY efficient, supported by the
distro, and it looks like:
- you'd be using linux guests anyway
- you'd have full control on all the guests

Exactly :)

FWIW, you didn't have to split it with partition (which will be hard
to modify later). Using LVM would probably be a better choice.

As Casey mentioned, the wiki is a good place to start. IIRC there
isn't a specific tutorial for squeeze though, so if you DO get it
working, please update the documentation there :)
