Run It All on One Box

You have one machine doing everything. A media server, a file share, an automation hub, all sharing one operating system, one package set, and one fate. Then an upgrade for one service breaks another, and there is no clean way back. Proxmox fixes that, but not for the reason most people say. The point is not virtualization as a technology. The point is that changes become reversible. Each service lives in its own isolated guest. Before a risky change you take a snapshot, and if it goes wrong you roll back in seconds. This book takes you from bare hardware to a running host with services on it: how to tell when you want a virtual machine and when you want a container, and why LXC containers are not Docker containers. How to install without losing the disk you meant to keep. How Proxmox storage actually works. How to build your first container and your first virtual machine. How to snapshot, and where snapshots stop being enough. How to take backups you have actually restored, because an untested backup is not a backup. You will also be told where this is not worth it, where passthrough gets fiddly, and why one box is still one box. By the end you own a machine where mistakes stop being permanent.
