Proxmox will not run on a standard Raspberry Pi
Proxmox VE — the virtualization platform that lets you run multiple virtual machines on one physical device — requires an x86 or x86-64 processor. Raspberry Pi boards use ARM processors, which Proxmox does not support. If you have a Raspberry Pi 4 or 5 sitting on your desk right now, Proxmox will not install on it.
This is a hard limitation, not a workaround situation. Proxmox's entire architecture is built around Intel and AMD chips. The installer will refuse to run, and even if you forced files onto the device, the system would not function. You need either a different hypervisor designed for ARM, or a different physical device.
The confusion usually comes from seeing both "Proxmox" and "Raspberry Pi" in the same sentence online. What those articles are actually describing is running Proxmox on an x86 mini PC or laptop, then using Proxmox to manage virtual machines that might eventually run on a Raspberry Pi. That is a different setup entirely.
Key Takeaways
- Proxmox requires an x86 or x86-64 processor and will not run on ARM-based Raspberry Pi boards under any configuration.
- If you want virtualization on a Raspberry Pi, use KVM, Docker, or LXC containers instead — all are designed for ARM architecture.
- If you want to use Proxmox, you need an x86 mini PC, old laptop, or desktop computer instead of a Raspberry Pi.
- Proxmox on an x86 device can manage virtual machines running Linux, Windows, or other operating systems, but the host device itself must have an x86 processor.
Why Proxmox does not work on ARM processors
Proxmox is written in C and Perl and compiled specifically for x86 and x86-64 architectures. The binaries — the actual executable files — are built to run only on those chip types. When you try to run an x86 binary on an ARM processor, the CPU simply does not understand the instructions. It is like trying to play a DVD in a CD player: the format is incompatible at the hardware level.
The Proxmox installer checks your processor type before it even begins. If it detects an ARM chip, the installation stops immediately. You cannot bypass this check without recompiling Proxmox from source code for ARM, which would require months of development work and is not something the Proxmox team has done or plans to do.
Raspberry Pi's ARM processors are excellent for their intended purpose — running lightweight Linux distributions, Docker containers, and single applications efficiently. But they were never designed to host a full hypervisor managing multiple virtual machines. The performance would be poor even if the architecture matched.
What to use instead on a Raspberry Pi
If you want to run multiple isolated environments on a Raspberry Pi, use Docker or LXC containers instead. Both are lightweight, designed for ARM, and let you run separate applications in isolated spaces without the overhead of full virtual machines.
Docker is the easier choice if you are new to containers. You install Docker on Raspberry Pi OS, then pull pre-built container images from Docker Hub. Each container runs a single application — a web server, database, or other service — in its own isolated environment. Containers start in seconds and use far less memory than virtual machines.
LXC containers are closer to virtual machines but still lighter than Proxmox. They let you run full Linux distributions inside containers on your Raspberry Pi. If you need something that feels more like traditional virtualization, LXC is the ARM-compatible option.
KVM (Kernel-based Virtual Machine) is also available on Raspberry Pi 5 with certain kernel configurations, though it is not officially supported and requires manual setup. It is slower than on x86 hardware and best used only if you have a specific reason to run full virtual machines rather than containers.
Using Proxmox on an x86 device instead
If you want to use Proxmox itself, you need to move to x86 hardware. This does not mean buying an expensive server. Used mini PCs, old laptops, or desktop computers all work fine. Look for devices with Intel Core i5 or newer, or AMD Ryzen equivalents. Even a 10-year-old laptop can run Proxmox and host several virtual machines.
Proxmox runs on bare metal — you install it as your main operating system, not inside another OS. Download the Proxmox VE ISO from proxmox.com, write it to a USB drive, boot the x86 device from that drive, and follow the installer. The process takes about 15 minutes. After installation, you access Proxmox through a web browser on another computer on your network.
Once Proxmox is running, you can create and manage virtual machines running any operating system — Linux, Windows, or others. You can also run LXC containers inside Proxmox if you want lightweight isolated environments alongside full virtual machines. This gives you flexibility that a Raspberry Pi cannot match.
Comparing your actual options
| What you want | Best choice | Hardware needed |
|---|---|---|
| Run multiple apps isolated on Raspberry Pi | Docker containers | Raspberry Pi 4 or 5 |
| Run full Linux distributions on Raspberry Pi | LXC containers | Raspberry Pi 4 or 5 |
| Use Proxmox to manage virtual machines | Proxmox on x86 mini PC or laptop | Used x86 computer (Intel/AMD) |
| Manage Raspberry Pi devices remotely | Proxmox Backup Server or Ansible | Separate x86 computer |
Running Proxmox on x86 hardware to manage multiple Raspberry Pis
One legitimate use case combines both: run Proxmox on an x86 device, then use Proxmox to manage virtual machines that you later deploy to Raspberry Pi clusters. This is an advanced setup, but it works. You develop and test on Proxmox, then migrate the virtual machine images to Raspberry Pi devices running KVM or containers.
Proxmox Backup Server — a separate tool that runs on x86 — can also back up and manage multiple Raspberry Pi devices across your network. This gives you centralized control without requiring Proxmox to run on the Raspberry Pi itself.
If you are building a home lab or small business infrastructure, the typical approach is: run Proxmox on one or two x86 devices as your main hypervisors, use Raspberry Pis for lightweight tasks like DNS, Pi-hole, or media servers, and manage everything from the Proxmox web interface.
Frequently Asked Questions
Can I install a lightweight version of Proxmox on Raspberry Pi?
No. Proxmox has no lightweight version for ARM. The entire codebase is x86-only. There is no stripped-down or minimal build that would work on Raspberry Pi. If you need hypervisor functionality on ARM, KVM or LXC are your only options.
What if I use a Raspberry Pi 5 with the latest kernel?
Raspberry Pi 5 is still ARM-based, so Proxmox will not run on it. The newer processor is faster, but it is still ARM architecture. Proxmox requires x86 or x86-64, period. A faster ARM chip does not change this limitation.
Can I run Docker inside Proxmox on an x86 device?
Yes. You can create a virtual machine inside Proxmox running Linux, then install Docker inside that virtual machine. This gives you nested containerization — containers running inside a virtual machine inside Proxmox. It works but adds overhead, so it is usually better to run Docker directly on the x86 host or in an LXC container within Proxmox.
Is there any way to make Proxmox work on Raspberry Pi?
Only if you recompile Proxmox from source code for ARM architecture, which would take months and require deep knowledge of virtualization systems. The Proxmox team does not support ARM and has no plans to. For practical purposes, the answer is no.
What x86 device should I buy to run Proxmox?
A used Intel NUC, Lenovo ThinkCentre, or Dell OptiPlex mini PC costs $100 to $300 and runs Proxmox well. You can also use an old laptop with an Intel Core i5 or better. Avoid Chromebooks and tablets — they use ARM or other non-x86 processors. Check the processor type before buying.
