От boot-кода до shell: несколько месяцев разработки ОС на Rust с ИИ-агентами
Как разработать собственную ОС в одиночку, если заниматься проектом можно только в свободное время? Рассказываю, как ИИ помог мне пройти путь от изучения AArch64 до работающего ядра с вытесняющим планировщиком, userspace, ELF-программами и shell — и почему ответственность инженера при этом никуда не исчезает.

Wie man #QEMU und #Virt-Manager installiert und danach ein Windows mit den #Virtio-Treibern installiert.
Mir hat schon immer eine Erklärung für den Virt-Manager gefehlt, die vom Anfang zum Ende führt, weswegen ich schon öfter die Virtualbox verwendet habe, die aber auch öfter Probleme hat. Weswegen ich das hier für mich und andere einmal zusammenfasse.

Lately I've seen a bunch of people struggeling with
libvirt QEMU/KVM setups where they want to bridge the VMs tdirectly to their LAN.
As I was re-installing my aarch64 host for test VMs on Chimera Linux the other day I figured I'll do a quick write up.
Chimera's libvirt comes with Modular driver daemons.
If your distribution runs the Monolithic driver daemon and or uses systemd or an other init system then dinit pleasue consult their documentation for that part of the installation.
The Bridge config part works on any distribution that uses NetworkManager.

Iată o postare optimizată pentru Mastodon despre noul stack HWE de virtualizare pentru Ubuntu 26.04 LTS, direct în limba română și fără menționarea vreunei surse:
🖥️ Ubuntu 26.04 LTS primește un stack opțional HWE pentru virtualizare!
Canonical extinde conceptul de Hardware Enablement (HWE) – folosit până acum în special pentru kernel – și către tehnologiile de virtualizare. Administratorii de sistem pot acum accesa cele mai noi versiuni ale pachetelor de virtualizare direct pe sistemele Ubuntu 26.04 LTS, fără a renunța la stabilitatea oferită de o versiune cu suport pe termen lung.
✨ Principalele detalii despre HWE-ul de virtualizare:
📦 Componente modernizate în mod continuu:
• Include pachetele dedicate qemu-hwe, libvirt-hwe, edk2-hwe (firmware OVMF) și seabios-hwe.
• Aceste pachete vor primi actualizări dinamic la fiecare 6 luni, preluând versiunile din lansările interimare Ubuntu.🔐 Sincronizare cu tehnologiile moderne de Confidențialitate (AMD SEV-SNP & Intel TDX):
• Facilitează adoptarea rapidă a noilor funcționalități hardware pentru Confidential Computing, AI confidențial și izolare avansată a mașinilor virtuale.⚙️ Complet opțional și sigur:
• Instalările standard vor păstra versiunile implicite de virtualizare. Activarea se face la alegerea administratorului.
• Canonical oferă instrumentul ubuntu_virt_helper pentru a gestiona întregul stack ca un ansamblu unificat, prevenind neconcordanțele de versiuni între QEMU, libvirt și firmware.🚀 Soluția ideală pentru centre de date și Cloud:
• Elimină dilema de a alege între o versiune interimară cu pachete noi și o versiune LTS stabilă – oferind acum ce este mai bun din ambele lumi.O evoluție excelentă pentru infrastructura enterprise pe Linux! 🚀

x86 stuff on ARM. #QEMU seems to ne the thing.

Most people are running containers on VM. But for some cases, I tried the opposite way on Fedora CoreOS: running VMs on qemu container.

Running libvirt's Virtual Machine Manager (virt-manager) on Linux and seeing a blurry VM console?
With a simple change in the settings the blurry text disappears and is crystal clear again.
A quick fix that might save you some frustration. #Linux #KVM #QEMU #VirtManager #OpenSource

🚀 Oh, joy! Someone decided to #rewrite #Linux 0.11 in #Rust, because clearly, what it needed was more hipster cred and extra bugs! 🙃 And surprise, surprise, it boots in QEMU—exactly where all the cutting-edge tech goes to die. 💀

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.

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?

backed up my iBook G3's 30GB HDD to another newer drive in case it failed on me as it is 24~ years old.
I also got it running QEMU, faster than the actual hardware with a bigger clock speed and more RAM.
(700~ -> 900MHz, 256 -> 512MB)
It last woke up on the iBook G3, now it's woken up in a QEMU PPC VM running on Apple Silicon.
I'm really impressed that it just worked.

Linux Frage: Nutze unter Debian quemu als hypervisor/Vitualisierungs-Enige. In einer virtuellen Maschine nutze ich omnissa horizon client (vmware). Bei suspend/resume am Gast-OS friert das Durchreichen von Tastatur-/Maus-Events an den horizon Client/die Remote-Sitzung ein. Das lässt sich z.B. reaktivieren, wenn ich in einem terminal unter dem Gast-OS eine Tastatureingabe tätige. Andere (Konfig-Lösungen) habe ich nicht gefunden. Ideen?

IronCurtain + GLM 5.2 found QEMU memory-corruption primitives from scratch, then almost autonomously chained the public EDU teaching device into a reproducible guest/host escape.
EDU is not production attack surface, which is why I can show the full chain. Findings in real configurations stay withheld.
What I want to highlight is that open-weight models, with orchestration and evidence gates, can now do serious vulnerability discovery and long-horizon exploit engineering.

“what are you trying to do now?”
you might be asking.Colima on macOS Ventura and later uses the Apple-supplied 'vz’ engine.
#newOldiMac is running Ventura.
So maybe docker was interacting poorly with that engine, especially because it was the first macOS version with it… maybe it's buggy?
So I'm installing ‘qemu', which is the native colima engine on all pre-Ventura Macs and Linux.
building it is taking a bit…

I said I wasn't going to fiddle around with my #selfhost #footiMac #newOldiMac anymore... well.

Listening to Antoine Ginies of #SUSE talking at #oSC26 about:
virtui-manager text-based Terminal User Interface application for managing #QEMU/#KVM VM
https://events.opensuse.org/conferences/oSC26/program/proposals/5100
I'm a #vmware user from version 1.0, but I suspect that it's time to learn about alternatives...

Some people asked about performance, so here is a video of #RISC_OS #Merlin booting (instantly) and running a graphics demo in #QEMU, Merlin is using its own software framebuffer in this demo, not yet GPU acceleration:
-
#RISC_OS: I finally had a bit of time to upload a video with the first system boot into graphic demo for #MerlinOS It works fine on @raspberrypi 2, 3 and 4, but the video is from #QEMU which makes it easy to record both #kernel logs and Pi 2 display. Enjoy!
