Build a VPS Host with Ubuntu Server 8.10 and KVM

It's written with the beginner in mind, and doesn't go into the nitty-gritty of paravirtualized VMs, custom networking configurations, or LVM-based virtual machines. Still, I think it's a good starting point for folks who want to experiment with virtualization on their LAN, and happen to have a spare computer laying around. Enjoy :).
