Ok, I'm sure Proxmox is great & all, but doesn't seem to work well on my NUC.

The network will just drop on the host randomly. We were watching something off of the Plex server yesterday when we see "connection to the server lost" and then suddenly all of the content just disappears. Try to log into Proxmox to see what's up and lo & behold I'm once again unable to log into the web interface.

Log into the box directly and it's responsive, run a few commands and
all of the VMs are up, but there's no network connectivity. Reboot the host and all comes back online. I got a USB3 NIC from Amazon & disabled the internal NIC, that seemed to work for a week & then same thing happens.

Reading online it looks like Proxmox & Intel NUCs don't play very well together, or at least haven't since version 8. My specific model is NUC10i7FNH.

It looks like ESXi has a free version again, so considering going back to
that as it ran fine for years without any issues. I also have a Windows Server 2019 license (which might also work to activate Server 2022) that I could use to run Hyper-V instead.

Does anyone have any thoughts?

That's weird - Proxmox is essentially Debian with a web front-end,
you'd think the upstream distros would see similar issues?

ESXi is a good platform, I found the hardware compatibility sketchy -
and I've got a crap homelab at home, so I didn't even bother setting it
up. I had 4-5 year old servers fall off VMWare's HCL a couple of years
ago, which didn't make sense.

Hey Warpslide!

You may want to read up on what this free version offers now. I don't think it's anything like ESXi was, to be honest.

Does anyone have any thoughts?

XCP-ng is another option. While it doesn't support containers, I'm sure it's great at running VMs. One thing I liked about XCP-ng over Proxmox was that it had a web interface as well as a console interface (rather than just a login prompt and a bunch of manual commands).

If you have a different machine (like a desktop where you can run Virtualbox on it), you can spin up any hypervisor you want to test out, and make your next decision based on something /you/ like, rather than something you were told to like. ;)

If ESXi is what works for you and your hardware, go that way. For ME, and my last-last-gen enterprise server hardware, Proxmox is the tits. It works, has plenty of expandability - and is the clear choice... but I don't care if you run Windows, Linux or MacOS... run what works for YOU. You made me want to play around w/ ESXi on my new Dell r730xd - and maybe I will. While I swear by Proxmox and Proxmox Backup Server, maybe something else works for you...

And thats fine. Run what you love. GO!

I started off on ESXi/vSphere, and after running proxmox for a while, I
don't think you get much more with either package with one system. If
you have enough systems for a cluster, managing it all through vCenter,
setting up high availability, really using vSphere, it's pretty cool.

I haven't had enough systems to look at setting up proper clustering
with Proxmox, however. For my needs, being able to manually move a
server to another node for maintenance is good enough.

I keep wanting to get 3 1l USFF systems and create a proper cluster,
but mine works well enough and I hate replace crap that works...

I have 3 Proxmox nodes, so I run enough servers that that might be a bonus. I currently don't have HA but its on my timeline... I find that often what we start with is just what we always wanna use in the future.

Howdy,

Reading online it looks like Proxmox & Intel NUCs don't play very well together, or at least haven't since version 8. My specific model is NUC10i7FNH.

Oh, I have the same NUC. And yes, mine is running ESXi and hasnt missed a beat since I got it years ago.

I just moved everything off it to my Pi CM5 cluster, which is also running proxmox and that has been running well. I did have 1 node go offline for a strange reason, and the backups of some containers seemed to be frozen very early on in the setup (all happened the same night) - but a reboot (and disable those backups) has seen it run a couple of weeks now without missing a beat.

I was thinking of moving my NUC over to Proxmox (I need an intel CI/CD agent running to build x86 containers), so I might have to rethink that. Actually if I can dual boot it and run it for a while on proxmox, I might give that a go in case I have the same problems as you.

I guess you could go back to ESXi and run proxmox in a VM if you wanted to stay with proxmox. I must admit, I am liking it, and do like running the lxc containers for single workloads (or a docker lxc container that is separate from the others).

I couldnt get my docker swarm to run in the container (lxc) environment - would be good to have containers float between nodes - given that Im using ceph. That was only going to be temporary anyway, as I plan to play with talos...

I haven't moved off of Proxmox yet, I actually like it and kind of want to try making it work. Using an external NIC hasn't solved any issues, I've read somewhere else to try disabling "Intel Turbo Boost Technology" in the BIOS to see if it helps.

I haven't done that as of yet, as it is right now I seem to have to reboot the NUC once a week.

I disabled Turbo Boost in the BIOS and haven't had to reboot the NUC once since then. I think the option in the BIOS was called "Intel Dynamic Power Technology". The description for that option says: "Setting this off will disable Enhanced Intel SpeedStep Technology and Intel Turbo Boost Technology."

I'm back to using the built-in NIC, with the modifications I made in /etc/network/interfaces, all seems to be working as well.

I'll report back if there's any weirdness, but it seems to be sorted.

Good to know - thanks.

I havent got there yet with my NUC - been busy with other flashing lights, but I have drained it so its ready for now.

I'll have to see if my Proxmox server (a Thinkpad laptop) still has any power optimization settings in BIOS. I need to take it down and blow the dust out, and probably swap out the thermal paste soon, I'll take a look then.
