#hypervisor — Public Fediverse posts

@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 VirtualBox

So without dwelling on the past or further ado, let's follow Jonathan's tour, shall we?

Proxmox: Ihre umfassende Lösung für Virtualisierungen

Proxmox VE (Virtual Environment) ist eine leistungsstarke und vielseitige Open-Source-Plattform, die Ihnen umfangreiche Möglichkeiten zur Virtualisierung und Containerisierung bietet.

Ich muss mir unbedingt merken, dass die langsame Reaktion auf IPIs, die in QEMU KVM nicht über Hypercalls ausgelöst werden, die Performance katastrophal beeinträchtigen kann, wenn ich das nächste Mal einen Kernel mit QEMU als Zielsystem schreibe. Mir graut es davor, herauszufinden, ob QEMU MTTCG ähnlich betroffen ist, da es im Mainline-QEMU keine solche Hypercalls gibt.

I need to make a mental note of the fact that slow responsiveness to IPIs not issued via hypercall in qemu KVM can pathologically degrade performance for the next time I'm writing a kernel using qemu as a target system. I'm terrified of finding out whether qemu MTTCG is similarly affected, because it has no such hypercalls in mainline qemu.

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?

Are there seriously no big companies using #citrix on a #Proxmox #hypervisor? Just because there is no support its not feasible at all? Are we really dependent on some other #BigTech company when moving from #VMWare?

Xen Hypervisor – Open-Source-Virtualisierung für Systemadministratoren

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 browser

That 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 browser

Yes. There is no need for extra runtimes in #firmware or a #hypervisor. Consider those optional, not mandatory.

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?

#Homelab #Linux #SysAdmin

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.

For anyone still using or considering the free #oVirt as virtualization management platform:⚠️ Please don't. It is a broken nightmare on community life support.⚠️

After #RedHat has ended support for its commercial spin Red Hat Virtualization (RHV) last year the development of oVirt practically came to a halt.

There hasn't been an official stable release for over a year despite security issues, and numerous bugs. The official recommendation is to use nightly releases to get the latest fixes. Too bad you won't be able to roll back via DNF if an update fails because older nightly releases are gone from the repo.

And yes, nightly releases do break oVirt at times. The latest nightly causes updates to fail because of incomplete dependency changes.

The web interface of the official mailing list is offline most of the time, the documentation is a confusing and outdated mess.

Upgrades to newer Linux distribution releases such as RHEL 9 or even 10 based systems are extremely painful and not officially supported.

Move your VMs to #ProxmoxVE or any other actively maintained KVM based solution.
