Slackware has always been a fantastic environment for development, and officially adding QEMU 10.2.2 to -current just confirms that! 🐧

ap/qemu-10.2.2-x86_64-2.txz: Rebuilt.
Recompiled against libcacard-2.8.2, libslirp-4.9.1, spice-0.16.0,
and usbredir-0.15.0.
Thanks to Daedra.
ap/qemu-guest-agent-10.2.2-x86_64-2.txz: Rebuilt.
l/graphviz-14.1.4-x86_64-1.txz: Upgraded.

Needed by qemu-10.2.2.
Thanks to Matteo Bernardini.

n/spice-protocol-0.14.5-noarch-1.txz: Added.
Needed by spice-0.16.0.
Thanks to Matteo Bernardini.
Think about it: a clean, solid base system, LXC for containers, and now native QEMU for full virtualization. Everything a developer needs, no fluff, straight from the core tree.

Slackware doesn't make noise. It just delivers. πŸ’ͺ

#Slackware #QEMU #Linux #Development

A couple of weeks ago I used #gemini to whip up a prototype of WFxT support for #qemu: https://patchew.org/QEMU/2026022412101[email protected]/

This week I posted my hand written series doing the same thing: https://patchew.org/QEMU/2026032013060[email protected]/

Compare and contrast the approaches. While #genai can get you a working prototype pretty quickly the result was hard to review and missed an important source of events as well as a sub-optimal implementation. This might not matter for one-shot code but for production it missed the mark.

@popey out of interest what display device did you give your riscv and s390x #qemu machines? Using virtio-gpu should offload a lot of processing from the slow emulation making for a reasonably snappy UI experience.

Hype for the Future 139G β†’ How to Install Virtual Machines for QEMU

Introduction With the Quick Emulator system, depending on platform and system architecture, the proper syntax for opening the virtual machine command is qemu-system-, where arch is the particular architecture in question. On select types of systems, such as ARM (32-bit qemu-system-arm and 64-bit qemu-system-aarch64), a specific machine configuration is required, using the -machine or shorthand -M command flag and associated parameter. Even though ARM virtual machines support -M virt, […]

Some users have already addressed this in the post.
https://www.linuxquestions.org/questions/slackware-14/latest-changelog-for-slackware-current-4175698890/page174.html#post6625656

As for the other features, I don’t really use them, I usually just spin up the VM and access it via SSH, so all I really need is libslirp (https://slackbuilds.org/repository/15.0/libraries/libslirp/?search=libslirp).

@bri7 @jasongorman idk what algorithms is the code for a bootable image of Linux is based on , but we boot it on 2/3 partitions of whole disk and full ram
Idk even non devs experiences system ve been hanging and breaking even for non coder Linux enthusiasts since way before ai
Ask physics undergrads :D
let me qualify my point with an example #qemu
QEMU uses various algorithms for different functionalities, including dynamic binary translation for emulating processors, and specific algorithms for block devices, disk images, and cryptographic operations. Additionally, it employs the Tiny Code Generator (TCG) for just-in-time compilation and optimization of code execution.
d you order them from best to worst ?

Je retombe sur un cours introductif aux conteneurs et Γ  la virtualisation que j'ai donnΓ© il y a quelques annΓ©es.

#qemu got added to #slackware current today. Didn’t see that one coming at all. Interesting times in the land of slack!

Hype for the Future 137D β†’ What to Expect from Virtualization Videos

Introduction When novaTopFlex creates videos involving the presence of virtual machines, expect the display resolution of the display to be recorded using the ffmpeg command to be set to 960x540. The ffmpeg command-line parameters should be set as follows: ffmpeg -f pulse -i default -f x11grab -framerate 60 -draw_mouse 0 -i .mp4 Virtualization Standards More information will be available directly within the video comments at https://www.youtube.com/@novaTopFlex.
