In the next ~6 months I’m going to entirely overhaul my setup. Today I have a NUC6i3 running Home Assistant OS, and a NUC8i7 running OpenMediaVault with all the usual suspects via Docker.
I want to upgrade hardware significantly, partially because I’d like to bring in some local LLM. Nothing crazy, 1-8B models hitting 50tps would make me happy. But even that is going to mean a beefy machine compared to today, which will be nice for everything else too of course.
I’m still all over the place on hardware, part of what I’m trying to decide is whether to go with a single machine for everything or keep them separate.
Idea 1 is a beefy machine and Proxmox with HA in a VM, OMV or TrueNAS in another, and maybe a 3rd straight Debian to separate all the Docker stuff. But I don’t know if I want to add the complexity.
Idea 2 would be beefy machine for straight OMV/TrueNAS and run most stuff there, and then just move HA over to the existing i7 for more breathing room (mostly for Frigate, which could also separate to other machine I guess).
I hear a lot of great things about Proxmox, but I’m not sold that it’s worth the new complexity for me. And keeping HA (which is “critical” compared to everything else) separated feels like a smart choice. But keeping it on aging hardware diminishes that anyway, so I don’t know.
Just wanting to hear various opinions I guess.

I will always recommend Proxmox, not just because it’s really easy to add more stuff, but because it’s really safe to tinker with. You take a snapshot, start messing around, and if you break something you just revert to the snapshot
This. Even if you were going to run a bare metal server it’s almost always nicer to install Proxmox and just have a single VM
This is how I run my OPNsense router. Snapshots are great and rebooting is SO much faster!
From an earlier post I made much like yours, I decided to go with incus. I’d be fully migrated if real life hadn’t kicked me in the taint for a few weeks.
It’s great if you need what it offers. Otherwise, it’s simpler to set up something like Ubuntu Server.
I use Proxmox to run my email service, https://port87.com/, because I can have high-availability services that can move around the different Proxmox hosts. It’s great for production stuff.
I also use it to run my seedbox, because graphics in the browser through Proxmox is really easy.
For everything else (my Jellyfin, Nextcloud, etc), I have a server that runs Ubuntu Server and use a docker compose stack for each service.
I’ve been using Ganeti for like 15 years now, and I’m not sure what proxmox offers besides a nice GUI. I know how Ganeti works and getting up to speed on a new one doesn’t seem super interesting to me. Is anyone here familiar with both?
Ganeti development is more or less dead. If you look at the github repo, it hasn’t seen a notable release in 4 years. All that’s been done is a small bugfix patch two months ago by the community.
The project being based on Haskell code also makes it less attractive for new devs.
Proxmox is a convenient gui wrapper around libvirt but you can do everything without it.
but you can do everything without it.
yes but why would you? There’s a reason we use GUIs, especially when new to a field (like virtualization).
libvirt comes with some gui tool of its own, though I haven’t used it. I generally prefer to understand what I’m doing, so I use command line tools or API’s at first. GUI’s are a convenience to use later, once it’s clear how they work.
yes but why would you?
Mainly because you’re required to use their distribution, or to build on Debian, which is not to everyone’s liking.
Of course that’s an argument against proxmox, and not
virt-managerand the like.
It’s got more than just VM management, but yeah, it’s a frontend for a bunch of other services, that you don’t need Proxmox for.
In my opinion, Proxmox is worth it for two reasons:
-
Easy high-availability setup and control
-
Proxmox Backup Server
Those two are what drove me to switch from KVM, and I don’t regret it at all. PBS truly is a fantastic piece of software.
-
Proxmox adds a lot of complexity and a nice GUI. If you are fine with using the terminal, there is really not much benefit from Proxmox and the potential issues from the added complexity are IMHO not worth it. I am not a Proxmox expert though, so take this advise with a grain of salt 😅
Is it decently easy to create and manage vm’s and containers with the terminal? I use proxmox at the moment. Should I switch to Ubuntu server?
Should I switch to Ubuntu server?
Thats a hard no IMO.
Even if you want to do something other than proxmox (just use Debian, fedora, or opensuse).
Its not bad from the CLI, you just need to know your commands.
virt-install --name=deb13-vm --vcpus=1 --memory=1024 --cdrom=/tmp/debian-13.0.0-amd64-netinst.iso --disk size=8 --os-variant=debian13Will get you 1 vcpu, 1GB ram, and an 8GB drive worth of debian. If you don’t specify a path, in home under .local/share/libvirt/images it will go!
You can also then
virsh edit deb13-vmAnd you’ll get the XML, where you can edit away.
Personally, I’d rather use the webgui for most things, but yeah its perfectly doable from the CLI.
I would have thought debian is better than ubuntu but I couldn’t find a server version of debian. Where do I find debian server or debian cli only?
Debian is by default suited for server. Just skip the desktop environment part in the installer.
Oh ok, I’ve never installed debian before so thats good to know.
With libvirt it is fairly easy yes. And you can also install a standalone web-gui like Cockpit or use the desktop app virt-manager over ssh to do it.
For me, I’m Team Proxmox. It’s just easy to spin up containers for pretty much anything I need. No need for the resource overhead of a full-on virtual machine if I simply need to run a LAMP app. Anything you really have an issue transitioning from Docker to LXC can still be run inside a container with Docker installed. And if you need to set up a VM for Windows or pfSense or some other OS for whatever reason, it’s insanely easy to do.
Not sure what youre doing with OMV that couldn’t be done in proxmox, so feel free to elaborate there.
Almost all my servers are proxmox (some just Debian, though a few more specific work related solutions are lurking about). For docker I’d do an LXC, btw, I wouldn’t bother with a full VM.
My (excessive) setup is all proxmox, set up as a high availability cluster. HA runs in a VM, and my USB devices are passed through (technically its USB over IP extension, so the USB devices for various VMs continually pass through even if I have to shut a server down).
Its where Jellyfin, Audiobookshelf, homepage.dev, a bajillion stupid containers I mostly dont need, DNS, monitoring and analytics, mealie (recipe server), various websites I host, etc, etc all live. Nothing is by itself on a box except my workstations, but for non-linux use I have VMs I remote into (mostly industry specific software and random crap like an xp VM to use an old piece of hardware).
Don’t use Proxmox, use incus. It’s way easier to run and doesn’t give a care about your storage.
No backup utility like PBS though, thats why I haven’t switched.
I did it purely so I could fully back up my server VM and move it to new hardware when I wanted to upgrade. I just have to install Proxmox, attach the NAS, and pull the VM backup. And just like that everything is back to running just as it was before the upgrade! Now just faster and more energy efficient!
No.
I use Proxmox for Work and Hyper-V at home. Looking forward to retiring my old Hyper-V host and replace it with Proxmox because Hyper-V is a pain.
Virtualization really helps with reliability. In particular, by allowing you to quickly take snapshots before doing anything destructive and by streamlining backup and recovery.
Don’t add a layer of abstraction until you need it, or you have the free time to learn it well enough that it won’t cause you problems while you experiment.
Do you need clusters that can failure ver from one machine to another? Is yes, proxmox is good. If no, there are less complex options.
