I had several freezes of my old laptop that runs Proxmox due to a stuck CPU fan. I googled a bit and found an elegant solution for temperature reporting: a command_line sensor.
Nevertheless, it took several hours to configure it correctly (I forgot how to deal with ssh keys and similar).
I installed the ‘Terminal & SSH’ add-on in to home assistant.
I created SSH keys, put them into /config/.ssh folder, and copied to my proxmox server. Read these instructions. I’ve put something like this in my HA Terminal addon:
$ mkdir /config/.ssh$ ssh-keygen <em># generated ssh keys and when asked, i enter the folder /root/config/.ssh</em> $ ssh-copy-id -i /root/config/.ssh/id_proxmox root@MY_PROXMOX_IP <em># copy keys to my prox server</em>$ ssh root@MY_PROXMOX_IP <em>#try out if I can log on without password prompt, then exit</em>
I had to find out where my proxmox stores temperatures. I ssh’ed to my proxmox again, browsed folders and looked into files which one store temps. My AMD laptop stores it in /sys/class/thermal/thermal_zone0/temp.
It could be also …/thermal_zone1, 2, 3 or similar.
Then I pulled temperature data via SSH to HA terminal:
When I publish a blog post, the WordPress Activitypub plugin delivers the post to the #fediverse. This causes the CPU to heat to 75C+. I know it now, because I can track its temp. in HA.
So I had a bit of a unpleasant experience with #proxmox and trying to successfully do a PCI(e) Passthrough.
In my cluster, I have a few machines running on an AMD Ryzen 7 4800U with Radeon Graphics. Following the Proxmox WIki guide, I kinda managed to pass the APU into a guest.
The unpleasant side effect was that following that, the host then lost control over the remaining PCI devices too, as in IO, network, etc. First thing to happen of course was all OSDs on that host just disappeared.

Hi, I am using this little box with an intel n100
In #proxmox vm, to get a fast #nftables linux vm, should I select 1 socket 4 cores?
Or will nftables work the same speed on 1 core? #linux
Obligatory yearly toot about #FOSS so I can stay on #Fosstodon 🎉
I saw the other day that German state Schleswig-Holstein is going to switch to fully #FOSS. Which is great and hope it works out for them.
Having set up a fully (F)OSS (desktops, apps, servers, etc) IT env for a large non-profit, might I suggest proper enterprise support instead of a lone coffee-addicted sysadmin who tries to keep systems together with hopes, prayers and duct tape? 🥲
That is not to say that everything was bad. Users liked working with #LinuxMint (still my fav distro), #RocketChat and #NextCloud were popular as well. Zimbra as a mailserver was ok, there were a few complaints about the scheduling tool. #Jitsi worked well, at times. I'm trying to remember the other apps that we used.
We had in-house servers with I believe #Proxmox and #Ubuntu vm's on top, managed by #Ansible. That all worked really well. One or 2 Windows VM's for legacy apps.
#homelab Hello there. I have bought a beelink s12 pro. It has 16g memory on board. However, I have heard that a #intel n100 can run with 32G.
Who has an intel n100 or beelink s12 pro and can tell me what 32G memory works well with it?
Also I heard rumours it will run 32G but can never use more than 16G.
Any tips apreciated and please boost! #proxmox#linux#n100

「 The device supports up to 16GB DDR5 memory, can take an M.2 NVMe SSD and/or a 2.5-inch SATA drive for storage, and also provides two video outputs through HDMI and DisplayPort, as well as a few USB ports, an RJ45 console port, and optional support for WiFi and 4G LTE connectivity 」
@jbzfn what would ne a similar small form computer to host a #proxmox vm farm on at home? 32G of ram would be nice two nics and a decent cpu? #linux#homelab
It's nice that Proxmox is providing a tool to help people migrate off of VMware ESXi. I did things the harder way as I didn't have a spare machine to install Promox and shuffle VMs over while I cleared out my own ESXi servers before installing Proxmox on them.

A few weeks ago I bought a terramaster NAS (because it was the only device you could install other OSes like proxmox or truenas on it) and now UGREEN published a kickstarter with their new NASes which can do the same but are much newer in terms of hardware…
It's kinda mesmerizing watching the core speeds on one of the i7-12700Ts in the #Proxmox Cluster (the one that runs Tiggi.es presently) dynamically shift cores anywhere from 1400Mhz to 4.62GHz quickly, and on an as-needed basis. The low base speed saves energy, but it'll instantly pop cores up to speeds within its thermal/power limit envelope, so for lightly-threaded workloads, it can perform as well as beefier chips. #homelab#servers#cpu
I have a single-node #Proxmox setup with various services in containers and a #HomeAssistant VM. For example, https://blog.randomplace.online/ is hosted there. I needed a #Widnows build machine to build a work project, so I decided to spin up a new VM.
I got 10 minutes of build time and my server didn't die during the build. You can see the CPU load of two builds. There is plenty compute power left to serve my blog for that one visitor per month. Also, the Home Assistant VM was not affected.
Need to mention that the node is an #ASUS PN41 with 4-core Celeron N5100 and 16GB of RAM.
@tuxedocomputers What would you recommend as HW for running #Proxmox as an enthusiastic developer for personal educational use? Will it perhaps be a supported OS during ordering?
I have a #proxmox problem where it looks like id's in the webgui are wrong.
If I connect to the command prompt it connects to the wrong vm. #homelab
Anybody see that problem before?
And know what to do perhaps?
Happens on #alpine vm's without kvm-client running
My #Proxmox journey started a month ago. I moved all my all my #docker containers and #HomeAssistant VM from my #Synology NAS to a testing MiniPC with Proxmox.
This test was very positive, so I decided to move to a new server. I'm using a cluster to move my LXCs and VMs. I'm very impressed by how simple the process is for a newbie like me. I just need to remove my snapshots before.
Bisher habe ich gedacht, dass die Performance von #homeassistant auf einem #raspberrypi 4 mit Boot über SSD vernünftig ist.
Wurde heute Abend eines besseren belehrt. Habe Home Assistant auf den neuen Mini PC mit #proxmox umgezogen und die Performance war direkt spürbar besser.
Jetzt ist alles so wunderbar flott, wenn man sich durch das Interface klickt. 🤩
So I've got a ProxMox server in my home lab now, and I am absolutely loving the freedom to create and destroy VMs at whim. It takes away so much of the fear about messing up personal laptops or the primary NAS i rely on for our household. A tinkerer's dream.
Les presento mi próximo proyecto ñoño: Armar mi propio NAS
Voy a remplazar un Qnap de 2 discos por un sistema armado con 4 discos. Ya tengo el gabinete, fuente de poder, procesador, RAM, SSD (Reciclada de la que cambié en el laptop) y los discos duros los reutilizo del Qnap. Solo falta que me llegue la placa madre.
Voy a utilizar TrueNAS SCALE como sistema operativo.
