After coming close to running out of resources last week and having to re-purpose another device turning it into a 3rd Proxmox node, got me thinking....
So, I built a basic tool for rough guidance.
It calculates vCPU overcommit ratios and RAM allocation locally in your browser. Just pure client-side math so you don't accidentally OOM your hypervisor like I almost did.
Have a play with it here: https://unknownuniverse.uk/tools/proxmox-calculator.
More tools coming soon!

Virtualization is a turbulent topic. Enterprises use enterprise systems. What can the small businesses do? Bhyve is a strong system for them.

"If you establish an immutable, bare-metal Layer-0 #Hypervisor that handles 100% of the physical hardware initialization and presents a generic, unified interface upward, you completely decouple the hardware from the operating system."
tl;dr creating a bootable VM workstation OS would break the PC industry. The PC would be like a smartphone and the OS would be like an App. If the OEM shipped with this, then users could pick their own OS safely without needing to be a super nerd.

@jselea Thanks goes out to Jonathan for this (still quite relevant) tidbit. For those of us who spent a lot of time with Sun #Solaris up through Solaris 10 there's a lot to appreciate here.
Solaris has been parted out, but here is an Enterprise production scale incarnation that's worth a looksee and testdrive. It's really a shame that the Evil EllisonCo destroyed so much - just discarded it like trash, following aquisitions, and what they didn't toss out in the trash they dissappointed the developers so much that it spawned forks that exist to fill the vacuum to this day:
- MySQL ==> MariaDB
- OOo ==> LibreOffice (The Document Foundation)
- Sun Enterprise Servers - rebranded as Oracle boxes
- Sun Solaris 10 ==> OpenIndiana and others (OmniOS, for one)
- Sun VirtualBox - Oracle VirtualBoxSo without dwelling on the past or further ado, let's follow Jonathan's tour, shall we?

Wird es noch eine Zukunft für VMs und Hypervisor geben oder wird in Zukunft "alles" containerisiert sein? - Bzw. dienen die VMs irgendwann nur noch dazu die Containerumgebung/Kubernetes zu starten? Welche Dienste werden auch in Zukunft durch VMs bereitgestellt werden? Welcher Anteil wird mal sein?

RE: https://mastodon.social/@CyReVolt/116261204236818661
Truth be told: Today's systems are nested runtimes.
Servers be like: firmware runtime + Linux + cloud runtime
Clients be like: firmware runtime + Linux + web browserThat is, there is sometimes a hypervisor between firmware and OS.
Or you go with @oxidecomputer for servers, and you get: Illumos (derivative) + cloud runtime
Or a Chromebook for a client: Linux + web browserYes. There is no need for extra runtimes in #firmware or a #hypervisor. Consider those optional, not mandatory.

🐢💤 Breaking news: #OpenBSD can now pretend to be a real OS by running on Apple's #Hypervisor, thanks to a few lines of code wizardry. Who knew virtual invisibility on #macOS was the final frontier for OpenBSD? 🌌🤷♂️

I spent last week rebuilding my entire setup — migrating from #Unraid to #Proxmox.
New storage layout, new VMs, new containers, new automations.
It’s amazing how a clean slate can simplify everything and spark new ideas.Still tweaking, still optimizing, but honestly? Feels good to be back in the #hypervisor world.
Any of you doing winter homelab overhauls right now?

Wouldn't it be cool if we built a little bootable #hypervisor that could run #Android in a protected VM for grandma, making her old computer safe, fast, and simple, and then, because it's built on that same secure fabric, you could just add more computers to the network for instant backup, shared resources, and more fun?

Что такое виртуальная машина и чем она отличается от виртуальных систем
В комментариях к одной из моих первых статей на Хабре мне было предложено написать статью про виртуальные машины. Долго думал об этом, было много дел не располагающих к писательству, и вот собрался наконец. Начну с остренького. В ИТ есть только одна настоящая система виртуальных машин. Это zVM. Всё остальное претендующее на это название на самом деле является системами виртуальных ... систем. Давайте разбираться с котлетами и мухами.

#ProxmoxVE 8 to 9 Upgrade #Guide
This #tutorial walks through the in-place upgrade from #Proxmox8 to #Proxmox9, documenting each step along the way. Our goal was to ensure a smooth transition while preserving all existing #virtualmachines, #containers, and configurations. This guide covers verifying system health, updating repositories, performing the upgrade, and confirming the installation afterward, all from the #Proxmox Shell.
