#qemu — Public Fediverse posts

Here is another in a series of attempts to divine information from #qemu's issue tracker. I think this is showing that #AI #bugpocolypse reports tend to be verbose, a lot of sanitizer reports are probably mislabelled (quite often the agent will show the failure in a sanitized build) and having a decent test case correlates well with undeclared agent use. The "normal" size of reports for each class of device in (Untagged) for any tooling or TestCase.

The open-issue emotional roller coaster. 🎢

Hooray, there's an issue for this... oh no, it's been open since 2021! Issue affects nested #qemu virtualisation with #FreeBSD: https://gitlab.com/qemu-project/qemu/-/work_items/337

Как QEMU исполняет чужой код: изучаем Tiny Code Compilator изнутри

QEMU — это не просто виртуализация с KVM. Его главная cуперсила — способность запускать программы, скомпилированные для одной архитектуры, на совершенно другом процессоре. Безо всякой поддержки со стороны хоста. Например, запустить прошивку для ARM-микроконтроллера на x86-ноутбуке. Как это работает? Под капотом QEMU скрывается JIT-компилятор под названием TCG (Tiny Code Generator). В этой статье мы разберем его устройство на практических примерах для RISC-V и посмотрим, как инструкции превращаются из одного машинного кода в другой, как формируются блоки трансляции, и зачем там нужны longjmp и цепочки блоков.

Episode 30 of Dark Blue Weekly released. Yes, it's already the 30th episode and because of this, I've simplified the appearance of the article a little bit.

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

Anyone having a working #QEMU config for booting an old Windows XP?

It appears that "pc-q35-2.10" is no longer available. And with "pc-q35-10.1" it fails to boot with an error stating that the system isn't fully ACPI compliant.

Edit: Same for "pc-q35-4.2" which is the oldest one I can select.

Edit: This is my config right now (worked with "pc-q35-2.10"): https://privatebin.net/?149dc6d610a02133#Ff49yRgAuEtAoNRyFpXMgsw4yT89q4CZYydu2ksTvPSw

So, to allow a linux vm to access a directory from Fedora host with virtio-9p, I'll need to run:

# semanage fcontext -a -t svirt_home_t "/some/dir"
# restorecon -vR /some/dir

Idk why sealert offers this non-working solution instead. It's really weird.:

# semanage fcontext -a -t virt_image_t 'dir'
# restorecon -v 'dir'

Neste vídeo, vou te mostrar, passo a passo, como instalar o Gnome Boxes no Pop!_OS 22.04 LTS.

Antes de começar... A ideia inicial para o vídeo era ensinar como compilar a versão atual do Gnome Boxes, pois o repositório do Pop!_OS 22.04 oferece a versão 42...

Great benefit of going #nojavascript #nojs on your #SmallWeb is being able to have full access to your web over experimental or retro #os. I just did a merry #solstice status update on mine. From #mothra. Running on #9front in #qemu running on top of #twm in #termux running on low end #android tablet. And yes, you can have decent user experience on mouse oriented system without a mouse using just trackpad / touchscreen.

So, merry Solstice. May your knitting and your code flow freely.
