Always-on desktop workstation vs remote dev VM on the Proxmox cluster?

Hi all, I'm Priya. I run a small Proxmox setup at home and do DevOps work for a living. I'm stuck on a workstation question and want to hear how others decided.

The two options

  1. Keep a dedicated desktop on 24/7. It sits next to the cluster as a dev box. Local disks, a GPU if I want one, and everything is just there.
  2. Run a dev VM on the cluster and use a low-power laptop as a thin client. The laptop only runs a terminal, an editor and a browser.

What pulls me toward the VM

  • Power - I haven't measured the desktop's idle draw properly yet. I plan to put a smart plug on it for a week before deciding, because I don't trust my guess.
  • Reproducibility - a VM can come from a cloud-init template, be configured by Ansible, and be rebuilt from Git. A desktop slowly turns into a pet.
  • Snapshots and backups - rolling back before a risky toolchain change is nice. So is having the VM covered by the same backup jobs as everything else.
  • Access from anywhere - with Tailscale or WireGuard, the same environment is reachable from the couch or from another city.

What pulls me toward the desktop

  • The chicken-and-egg problem - if the cluster is down, I can't use my dev environment to fix the cluster. A separate machine is a useful escape hatch.
  • GUI and GPU work - terminal and editor workflows over SSH are great. Full desktop sessions over RDP, SPICE or something like Sunshine/Moonlight are where I'm less sure how it feels day to day. GPU passthrough on Proxmox also adds complexity I'd have to maintain.
  • Latency - remote editing is fine on a LAN. I'm unsure how it holds up over VPN on a bad connection.
  • Blast radius - a noisy build or runaway container in a dev VM shares CPU and RAM with services my family relies on, unless I limit it.

What I'm leaning toward

A hybrid, dev VM for most work, using VS Code Remote-SSH or similar from the laptop, plus one small, cheap local machine that is not a cluster member and can reach the management network. I'd only keep the full desktop if I have a real need for local GPU or GUI work.

A minimal SSH config for the VM approach would look like this:

Host devvm
    HostName devvm.lab.example
    User priya
    ForwardAgent no
    ServerAliveInterval 30
    ServerAliveCountMax 4

I'd keep the private key on the laptop, not the VM, and let the VM pull from my Git server.

Questions for you

  • If you've moved from a desktop to a remote dev VM, what did you regret or miss, and did you keep a fallback machine?
  • For anyone doing GUI work remotely, which protocol has actually held up for you on a home network and over VPN?
