Neuer Artikel: Proxmox vs Unraid für Anfänger: Welches System passt zu deinem Homelab? – https://rootwerkstatt.de/proxmox-vs-unraid/ #Proxmox #Unraid #Homelab #Vergleich #Anfänger

Any feedback of how much maintenance work a #Yunohost instance on #Proxmox requires? I'd really like to give them a try (as I only have a Debian on a Raspberry for now), but my health is so changing and unstable, I'm looking for something as simple as possible.

I could also try Yunohost on baremetal but I'd also like to be able to run a VM or two to deploy my own projects or test things. But I can sacrifice that if that makes maintenance considerably easier.

For context, I like computers but I can hardly cook myself three meals a day these times, so with all respect I have to sysadmins I don't want to manage and configure everything by hand...

Hello again, Fediverse, time for my #introduction

First off, this account exists mainly to hopefully get #fedihired hopefully so set expectations accordingly.
Boosts are appreciated.

With that out of the way, I am Dennis also known as DeKayy.
I am an OSS enthusiast currently living in the area around #Frankfurt , being fluent in both English and German.
Outside of technology, my passions lie with equality, equity, independence, generally making the world a better and more fair place.

A homelab and ever increasingly independent tech-stack is also what I call my own.

On the career side, I have been a System and Network-Administrator for nearly 4½
years and counting.

And as mentioned, currently on the lookout for new opportunities, preferable completely remote.

I manage around 20 #Proxmox nodes professionally and 3 in my personal deployments, the amount of #Debian VM's and containers (including #Docker) sits somewhere in the hundreds.
With #Ansible slowly getting established in every nook and cranny to help with the whole process.

Monitoring is done on both sides with #Zabbix and serving web-requests with either #Nginx and #Apache, though I prefer the former.

I use Let's Encrypt and Cloudflare quite a lot, also having built a certificate distribution framework to deploy those internally behind metaphorical split-brain DNS lines.

Windows Server and Puppet are also not unfamiliar to me, they are currently not frequent acquaintances.
In the direction of #DevOps experience, I use Git daily, I either setup, helped with or run Jenkins buildsystems, Gitlab instances, Gitlab-runners and more.

Development-wise I created applications, tools and helpers in C#, Java, Bash, Powershell, Lua and Python, in order of proficiency.

I bring enough social skills, experience, passion and conviction to help build and run an entire independent tech stack if one wishes for it and brings enough patience, time and budget.

What I am looking for is primarily a remote position, 60% work-from-home is my minimum.

This introduction post is getting kinda long so I will leave it here for now, reach out if you are interested.

Later, DeKayy

Выход за пределы KVM (KVM escape): выполняя действия исключительно со стороны гостевой системы, злоумышленник может скомпрометировать хост, на котором запущена его виртуальная машина. Например, арендовав всего один экземпляр (инстанс) в публичном облаке, атакующий может вызвать аварийную остановку ядра хоста (kernel panic), что приведет к отказу в обслуживании (DoS) для всех остальных виртуальных машин на этом физическом сервере, либо выполнить код с правами root на хосте, чтобы полностью захватить контроль над ним и всеми запущенными на нем гостевыми системами (RCE).

so i tried to make a nested proxmox vgpu thingy. but it doesnt work cause when i enabled viommu on the vm the nvidia driver fails(RmInitAdapter failed) but when i disable viommu mdev doesnt work cause it needs /sys/kernel/iommu_groups/ which only exsists with iommu. i fucking hate this bullshit.

@nico79 ich habe einen Dresden Electronic ConBEE-3.

Da mein #homeassistant als virtuelle Maschine in einem #ProxMox Cluster läuft, habe ich den Stick nicht direkt an dem Rechner, sondern an einer Raspberry die den USB Port über USB/IP bereitstellt.

Sollte eigentlich mit jedem USB Gerät gehen. Damit kann man die Antenne an strategisch besserer Stelle platzieren als den Rechner.

To #shutdown Proxmox cluster and prevent data loss or corruption, especially when Ceph storage is in use, you must follow a specific procedure.

[ Blog ] Nakivo #Backup and #Replication v11.1 released

The new #Nakivo Backup and Replication v11.1 has just been released offering powerful new features mainly focused to protect VMware, #Proxmox platforms, and physical machines.

A major improvement in v11.1 is the expanded set of functions available for the Proxmox environment, allowing to fully protect your workloads.

In a Proxmox environment, you may need to #extend root partition if it runs out of space.

To do this, you must first allocate additional storage on the hypervisor and then configure the system to perform the necessary operations.

During a Proxmox upgrade procedure, you may encounter failures caused by insufficient disk space http://rviv.ly/WXz3H1 #partion

If you are running Ceph Reef in your #Proxmox infrastructure and plan to upgrade to Proxmox 9, you must first upgrade Ceph Reef to Squid to meet the prerequisites.

As a best practice, before proceeding with the upgrade make sure to have a working backup of your VMs and Containers.

[ Blog ] How to properly #boot a migrated Windows vSphere VM in #Proxmox

To properly boot a migrated Windows vSphere VM in Proxmox during a migration, you must follow a specific procedure.

Windows VMs are quite sensitive to virtual platform changes. This is because the storage #controller configured in the source environment often causes issues, the mismatch between the original controller http://rviv.ly/vOiGHj

@theblazetrends Great, another spy / insecure app rather than making the web app useful. I can't even check the IP address of VMs on the web app FFS.

What is this obsession with native apps... yes, that's rhetorical. We all know why, and that #Proxmox are doing this is a red flag because we know.

Proxmox has released a native Android app for remote server management. It allows users to monitor nodes and control virtual machines directly from mobile devices. #Proxmox #HomeLab #Virtualization #OpenSource

Mettre à jour un serveur #Proxmox, c'est quand même un sacré stress...

Et misère, la version 8 n'est plus maintenue après le mois d'Août. Ça veut dire qu'il vaut que je passe en version 9 à présent, est-ce une bonne idée de le faire maintenant 🤔

@fox you know that there ist the #Proxmox-Datencer-Manager #PDM to connect multiple independent Clusters and/or multiple single machines, right?

This error prevents the Worker from deploying correctly and, consequently, stops you from backing up the Proxmox VE platform.

The Promox node for my pfSense router has been screaming at me ("BACK UP DATA NOW!") for two and a half weeks. Finally had a chance to acquire a used Samsung SSD from a local eBay seller and get everything migrated over. The old SSD was at 90% wear level when the alerts started appearing, and 97% by the time it was retired today. I like to live on the edge!

I have a #NixOS container that manages a wildcard TLS certificate stored in a mount shared with every nginx-using container. I used to have to restart #nginx everywhere whenever the certificate was refreshed. I just added two pieces:

1. A systemd `path` + `service` pair in each nginx-using container that calls `systemctl reload nginx` whenever the certs change.
2. A hacky daily service on one host that mounts the certs over Samba to sync local copies when changed.

Presto! Automation.

I have an lxc running a VPN, and where the host needs to access the internet (e.g. doing updates) I want to force that through the lxc VPN.

I dont want to interfere with local lan or cluster traffic - so just setting a default route isn’t appropriate. Likewise I’m not sure just installing the VPN on the host is the right idea.

I’m pretty sure there is a way of doing it… its just not coming to me 😅

Ich Held hab' mal wieder was zerbastelt:
Ich hab' eine (Qemu) VM auf einem Proxmox schlafen gelegt… also suspended… vom GUI der Maschine aus (via noVNC), nicht von der Weboberfläche des Proxmox aus.
D.h. für Proxmox ist die VM an, der noVNC-Viewer von Proxmox zeigt aber nur nen schwarzen Bildschirm und reagiert auf nix.

So. Hat jemand eine Idee, wie ich eine suspendete Qemu-VM wieder unsuspenden kann? Oder muss ich sie hart rebooten?
