Practical Homelab Guides for Proxmox and Self-Hosting

The short answer: Reuse a suitable computer before buying another one. Choose a compact mini PC when space and noise matter and you do not need many full VMs or internal drives. Compare an expandable used business PC when you need more VM headroom, several local drives, a PCIe card, or a flexible upgrade path. Check the exact model and configuration before buying; a chassis category alone cannot guarantee capacity, noise, or compatibility. ...

Kurzantwort Ein Intel N150 mit 16 GB RAM reicht für viele kleine Proxmox-Homelabs aus. Home Assistant, AdGuard oder Pi-hole, Monitoring und mehrere leichte LXC-Container sind für diese Geräteklasse plausible Aufgaben. Die wichtigere Frage vor dem Kauf lautet aber nicht nur: „Läuft Proxmox auf einem N150?“ Sondern: Reicht ein N150 für genau die Dienste, die ich gleichzeitig betreiben möchte? Bei Jellyfin-Transcoding, großen Immich-Importen, mehreren vollständigen VMs oder einer Windows-VM werden CPU-Leistung, RAM und Erweiterbarkeit deutlich wichtiger. Genau deshalb ist eine Workload-basierte Entscheidung sinnvoller als eine pauschale Mini-PC-Empfehlung. ...

If Proxmox says QEMU guest agent is not running, reinstalling the agent is often not the fix. First check that the agent is enabled in Proxmox, confirm the service is running inside the VM, and verify the virtio-serial channel. If the option was enabled while the VM was running and the channel is absent, a full stop and start from Proxmox is a sensible next step; reinstalling the guest package cannot create a missing host-side virtual device. ...

Wake-on-LAN failing on Proxmox? There are two completely separate problems people mean by this: Waking the physical Proxmox host from a full shutdown — this is regular hardware WoL. It works, with a few Proxmox-specific gotchas. Waking a VM that is powered off — classic magic-packet WoL does not work here. A virtual NIC is not a physical card sitting in a low-power state. If you mixed solutions from both threads and nothing worked, that is why. Do them separately. ...

A Proxmox backup can fail at 2 AM while everything else keeps running normally. Your VMs are still up. The host looks healthy. Nothing forces you to open the backup logs. Then a few days later you discover that the backup you assumed was running every night hasn’t been working. For backups, I don’t want another monitoring dashboard. I want this: ❌ PBS backup FAILED node pve1 · 02:14 One message when the backup breaks. ...

You already can run a raw Paper/Vanilla jar in an LXC. Crafty Controller is the layer on top: a web UI to start/stop servers, edit files, pull backups, and keep more than one Minecraft version without SSH-ing into the box every time. If you have not decided between LXC vs VM or Java vs Bedrock yet, start with the Minecraft Server on Proxmox guide . This article assumes that decision is made and focuses on how to manage those servers once they exist. ...

If an Intel I225-V interface on Proxmox VE 9 starts falling into a repeating NETDEV WATCHDOG / Reset adapter loop after moving to a 7.0.x Proxmox kernel, there is now at least one well-documented report showing exactly that pattern. The important caveat is scope: this is not yet a broadly confirmed Proxmox-wide bug affecting every I225-V or I226-V system. The strongest current evidence comes from one detailed Proxmox VE 9.2.5 report where the same I225-V hardware was stable on 6.17.13-21-pve and repeatedly failed on two tested 7.0 kernels. ...

If you’re building a Proxmox home lab, you don’t necessarily need a large server. A modern Mini PC can give you a surprisingly capable Proxmox host in a small, quiet package. The difficult part is choosing one that makes sense for virtualization, rather than simply choosing the Mini PC with the fastest benchmark score. For Proxmox, we care about: CPU virtualization support RAM capacity and upgradeability NVMe storage Ethernet connectivity PCIe/IOMMU capabilities cooling under sustained workloads power consumption expansion options price In this guide, we’ll focus on the GMKtec K8 Plus and Beelink SER8, two Mini PCs that make particularly interesting Proxmox home-lab hosts. ...

Evidence note: This is a research-backed analysis of the GMKtec K8 Plus as a Proxmox host. It combines GMKtec’s system specifications , AMD’s Ryzen 7 8845HS specifications , Proxmox documentation, and attributable owner reports. It is not a first-hand RunAHomeLab hardware benchmark. Community reports identify possible failure modes but do not prove that every unit is affected. See the research methodology .

An Active Directory lab is useful for learning domain controllers, DNS, Group Policy, identity administration, and Windows client management. This guide is a learning-lab plan, not a production Active Directory design or security baseline. Evidence note: The Windows and AD DS guidance below follows current Microsoft documentation; Proxmox-specific guest guidance points to Proxmox documentation. Resource values are conservative starting allocations, not measured performance guarantees. See the research methodology . What You Need a Proxmox host with enough spare CPU, memory, and storage for the guests you choose; a current Windows Server evaluation ISO from the Microsoft Evaluation Center ; one or more Windows client ISOs that you are licensed to use; the Windows VirtIO drivers when the VM uses VirtIO storage, network, ballooning, or serial devices; an isolated lab network if you plan to test DHCP, DNS failures, offensive-security tools, or intentionally unsafe configurations. Whether a Windows VM needs a specific VirtIO driver depends on the virtual hardware selected. It does not depend on whether the VM is a server or client, or how “important” the guest is. ...
