Eh… Not really. Qemu does a really good job with VM virtualizarion.

I believe I could easily build containers instead of VMs from the nix config, but I actually do like having a full VM: since it’s running a full OS instead of an app, all the usual nix tooling just works on it.

Also: In my day job, I actually have to deal quite a bit with containers (and kubernetes), and I just… don’t like it.

I’ll DM you… Not sire I want to link those two accounts publicly 😄

Zero.

About 35 NixOS VMs though, each running either a single service (e.g. Paperless) or a suite (Sonarr and so on plus NZBGet, VPN,…).

There’s additionally a couple of client VMs. All of those distribute over 3 Proxmox hosts accessing the same iSCSI target for VM storage.

SSL and WireGuard are terminated at a physical firewall box running OpnSense, so with very few exceptions, the VMs do not handle any complicated network setup.

A lot of those VMs have zero state, those that do have backup of just that state automated to the NAS (simply via rsync) and from there everything is backed up again through borg to an external storage box.

In the stateless case, deploying a new VM is a single command; in the stateful case, same command, wait for it to come up, SSH in (keys are part of the VM images), run restore-<whatever>.

On an average day, I spend 0 minutes managing the homelab.

You (sadly) need to group all quality profiles into a single one, and then handle quality through a custom format. Example from my setup:

NixOS for the win! Define your system and services, run a single command, get a reproducible, Proxmox-compatible VM out of it. Nixpkgs has basically every service you’d ever want to selfhost.

Lost me at LLMs. My Nix config is over 20k lines long at this point, neatly split into more than a hundred modules and managing 8 physical machines and 30+ VMs. I love it.

But every time I’ve tried to use an LLM for nix, it has failed spectacularly.

Sorry, unfortunately can’t help you there. My matrix server is not federated, I remember back then I created an account on matrix.org specifically to read these. But maybe they got deleted in the meantime?

Anyways, I have been really happy with continuwuity, to the point that up until now, I haven’t even looked at tuwunel again. The maintainers of continuwuity seem really nice and engaged, and both from a usage and stability point of view, as well as for the actually surprisingly fast release cycle, I have no complaints. I found and fixed a bug a couple weeks ago, and the dev process was also very friendly and relaxed.

In short: while I don’t know how things are on the tuwunel side, I’m very happy to have gone with continuwuity and have high hopes for the future of the project.

Almost 9k lunes of python in a bash script. Lmao. No.
