Quick verdict
| Your situation | Recommendation |
|---|---|
| You want full‑blown VM and container hosting on the same box (and don’t mind a learning curve) | Proxmox VE (affiliate) |
| You need a lightweight, plugin‑rich NAS that runs on Debian without fuss | OpenMediaVault (affiliate) |
If you’re building a homelab where both services are useful, consider running them side‑by‑side—e.g., Proxmox VE for VMs/containers and an OpenMediaVault VM or container for file storage.

Deep dive
1. What you actually get under the hood
Both products are pure software, meaning you can install them on any x86_64 hardware that your budget allows. Proxmox VE positions itself as a hypervisor—it boots directly onto metal and hands you a web UI for creating KVM virtual machines and LXC containers. The clustering support lets you scale out to multiple nodes, which is a huge win if you ever plan to grow beyond a single box.
OpenMediaVault, on the other hand, is an NAS operating system built on Debian. It boots into a lightweight Linux environment and presents a slick web console focused on storage: disks, RAID, SMB/NFS shares, and a thriving plugin ecosystem (Docker, SnapRAID, etc.). Because it’s light, you can even run it in a VM or container if you prefer to keep your hypervisor separate.
2. Learning curve vs polish
I’ll be honest—Proxmox VE feels like stepping into the world of enterprise virtualization. The UI is powerful but dense; you’ll spend time learning concepts such as “storage pools,” “bridge networking,” and “high‑availability groups.” That steep learning curve pays off when you need granular control over resources or want to run multiple isolated workloads.
OpenMediaVault’s interface is more plug‑and‑play. You add a disk, enable SMB, install the Docker plugin, and you’re done. The trade‑off is that it can feel less refined—some settings are hidden behind “advanced” tabs, and occasional UI quirks remind you it isn’t a commercial product with dedicated support.
3. Extensibility without breaking the bank
Both solutions thrive on community contributions. Proxmox VE’s built‑in clustering means you can add nodes later without buying licenses—everything stays free. OpenMediaVault’s plugin system is its secret sauce: from Plex to ownCloud, a simple click installs additional services while keeping the base OS light.
If your lab already runs Docker containers for other projects, you’ll find OpenMediaVault’s Docker plugin a natural fit. Conversely, if you need full VM isolation (e.g., Windows testing, nested Kubernetes), Proxmox VE is the only choice among these two.
