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
RHEL/Centos5.x.

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 :)
