Proxmox VE turns a compatible computer into a host for virtual machines and containers, managed from a web browser. To get started, check that the CPU supports virtualization, choose memory and storage for the workloads you plan to run, and install Proxmox on a dedicated machine. The installer can erase data on the disk you select, so back up anything you need before proceeding.
What Proxmox VE does
Proxmox Virtual Environment (VE) is a bare-metal virtualization platform: you install it directly on a physical host, then use that host to run and manage virtual machines and containers. You manage the host through a browser; a separate management application is not required. The USB drive or DVD used to start installation is only installer media. It is separate from the storage you choose for Proxmox and your virtual machines.
Proxmox’s official downloads listing showed Proxmox VE 9.2-1, updated May 21, 2026. The listing also showed an ARM64 installer, version 9.2-1-arm64, updated August 5, 2026. These details can change; check the official Proxmox downloads page for the current release before downloading. Proxmox’s VE datasheet listed version 9.2 with an update date of May 21, 2026.
What hardware do you need for a Proxmox home lab?
There is no single build that fits every home lab. Choose hardware around the guests and services you expect to run, then check that the host can accommodate their combined demands. Proxmox recommends Intel 64 or AMD64 systems with Intel VT or AMD-V; its requirements also list 64-bit Armv9-A or newer as an alternative. For x86 KVM full virtualization, both the processor and motherboard need Intel VT or AMD-V support.

CPU and virtualization
Verify the exact processor’s virtualization features before buying or installing. If you plan to pass a PCIe device through to a guest, Proxmox says the CPU must support Intel VT-d or AMD-Vi. Passthrough is an optional capability, not a requirement for a basic host.
Memory
Proxmox’s hardware requirements page, accessed October 7, 2026, lists 2 GB of RAM for the operating system and Proxmox VE services before allocating memory to guests. It lists 1 GB as the minimum for evaluation only. The same page says Ceph or ZFS needs additional memory, approximately 1 GB per TB of used storage. Treat these as published baselines, not a complete home-lab sizing recommendation: memory needs depend on the number and type of guests and services, and the requirements page does not set a universal total.

Storage and redundancy
Proxmox recommends fast, redundant storage and says SSD disks give the best results. Decide on the storage arrangement before installing. A simple local-disk setup can be easier to start with; a redundant arrangement can improve resilience to a disk failure, but does not replace a separate backup.
Proxmox describes two distinct approaches: hardware RAID with a battery-backed write cache, or non-RAID storage with ZFS. Its requirements page warns that ZFS and Ceph are not compatible with a hardware RAID controller. Do not put ZFS on top of such a controller.
Rank #3
Network and future expansion
Redundant gigabit network interfaces appear in Proxmox’s recommended hardware guidance, and the platform supports 10 Gbit and higher networking. NAS, shared, and distributed storage are also supported. These are options for particular needs or later expansion, not prerequisites for a basic single-host installation.
Is a mini PC suitable?
A mini PC can be a compact option for a low-demand lab if its exact processor supports the required virtualization features and it has enough memory, storage, and networking for your planned guests. That is a category-level possibility, not a recommendation for a particular model. Check memory upgrade options, drive capacity, network ports, and any passthrough requirements before choosing one.

How do you install Proxmox?
- Check compatibility. Review the official system requirements. Confirm CPU virtualization support and check that it is enabled in the machine’s firmware settings. Menu names vary by hardware, so consult the computer or motherboard documentation for the relevant setting.
- Download the installer. Get the current Proxmox VE ISO from the official downloads page. Confirm the release shown there rather than relying on an older version number.
- Create installer media. Write the ISO to a USB flash drive or CD/DVD. This media starts the installation; it is not a substitute for persistent host or guest storage.
- Boot the target machine. Start the dedicated host from the installer media and follow the installation wizard. For current screen-by-screen guidance, use Proxmox’s installation documentation.
- Select the installation disk carefully. Proxmox describes VE as a bare-metal installer and warns that existing data on selected disks will be removed. Identify the intended target disk and back up any data you need before continuing.
- Manage the installed host in a browser. After installation, use the web interface to configure and manage the host; a separate management tool is not needed.
Installation mistakes to avoid
- Assuming the installer USB is server storage: it is boot media, while persistent host and guest storage are separate choices.
- Installing over a disk without checking its contents: the selected disk’s existing data can be removed. Confirm the target and make a backup first.
- Choosing ZFS with a hardware RAID controller: Proxmox explicitly warns against combining ZFS or Ceph with hardware RAID.
- Buying to a generic RAM figure: the operating-system baseline does not include guest memory, and ZFS or Ceph adds memory needs. Size the machine for the workloads you actually intend to run.
- Treating advanced networking or shared storage as mandatory: these capabilities can support growth, but a basic single-host setup does not require them.
