This article is designed to introduce the process of PXE-booting a host directly into the Debian installer, and then automating the installation via the Debian PreSeed configuration. Both of these topics have been covered in the past, but not together - and we'll also include notes on testing this setup with KVM.
I've got a webserver which runs a particular service, and that service is sufficiently interesting and important that I run monitoring probes against it every 30 seconds. Those particular requests clutter my logs, and here is a brief note on how to avoid that clutter.
