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.
that didn't last. lol

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!

Легаси-ОС как тормоз виртуализации: что меняет современный стек РЕД ОС в VK Cloud
Представьте гиперноду облака. Гипернода — это физический сервер с запущенным гипервизором, на котором работают виртуальные машины клиентов. Под дисками этих машин лежит программно определяемое хранилище Ceph: распределенная система, где данные размазаны по многим серверам с копиями, без отдельного дискового массива. Меняем на ноде одну переменную — операционную систему. Виртуальные машины не пересобираем, кластер хранения не трогаем, диски и сеть те же. Ни одной новой железки, ни строчки нового кода в приложении. После переключения дисковая подсистема ВМ ведет себя ощутимо иначе. VK Cloud активно использует РЕД ОС от РЕД СОФТ — в том числе в VK Secure Cloud, аттестованном контуре для значимых объектов критической информационной инфраструктуры (ЗОКИИ). На ее примере покажу, как поднять производительность гипервизора, просто обновив легаси и не трогая железо. Вместе с дистрибутивом на ноду приезжает свежий стек целиком: ядро, эмулятор, клиент хранилища, системные библиотеки. Каждый слой подтягивает свой кусок. А для тех, кто застрял на CentOS, ушедшем в EOL, у истории есть вторая часть: обновление закрывает технический разрыв и регуляторику одним движением. Ниже разберу механику по слоям с командами, которые можно выполнить на своей системе.
