Proxmox VE is a free and open-source virtualization platform built on Debian. It supports KVM virtual machines, LXC containers, ZFS storage, clustering, backups, live migration, and high-availability features. For home labs, the big advantage is flexibility. You can run a Windows VM, a Linux server, Home Assistant, Docker, Pi-hole, Plex, Jellyfin, TrueNAS, or even pfSense on the same physical system. For small businesses or more advanced users, Proxmox can scale into multi-node clusters with shared storage and centralized management. The main tradeoff is that Proxmox is infrastructure software

We’ll be configuring a QDevice in this tutorial for Quorum. Quorum is used to ensure that most of the nodes in a cluster are online, with the overall goal being to have three total votes. The QDevice we’ll be setting up acts as the third vote without actually running the Proxmox OS. The steps below can run on any Debian-based device, but we’ll be using a Raspberry Pi specifically because it’s one of the cheapest options you can use. Remember, you don’t need a Raspberry Pi, but you do need it to be a separate device from the two Proxmox nodes, so any Linux system should work. This ensures that
