Good morning Fedi! Do any of yall use a operating system that's not Linux, Windows, BSD or Mac on a regular basis? If so, which one?

With #qemu (and probably others) explicitly disallowing AI generated code, but keeping the same license, there's bound to be some fun when people have code coming from other code bases which allow it; e.g. @kees playing with a few bits in the #linux kernel (mostly test though).

well this is an interesting #qemu patch which in some ways implements to the pre-TCG days of stringing gadgets together: https://patchew.org/QEMU/20250722174228.16205-1-j@getutm.app/

It's a workaround for the lack of #JIT support on #ios which is why #utm's emulation is really slow. It's the only production use of the TCG interpreter I'm aware of - we have backends for 9 different architectures so most people have to go out of their way to use the interpreter.

My first #podcast appearance has finally gone live. SAP's "The Open Source Way" is a regular podcast looking at various #floss projects. This week Karsten talks to Helge and myself about #qemu, its capabilities, development model and project governance.

One Linux phone to rule them all

Booting iOS 14 on #postmarketOS using #QEMU

Does anyone here know how to run #Amazon Linux 2 or 2023 #aarch64 #QEMU images? They seem to hang right after exiting boot services. Latest qemu and #EDK2 i could get on Fedora 42.

Perhaps @hrw knows, or knows someone who knows.

When researching for one of my last articles, I noticed a speed difference between RHEL7 and RHEL10. I used these 2, but the observed speciality can also be seen on (all?) other distros.

Got to the ground of it, might make a fun read for all involved with glibc and emulation :

“#QEMU project policy is to DECLINE any contributions which are believed to include or derive from #AI generated content. This includes #ChatGPT, #Claude, #Copilot, #Llama and similar tools.”

https://github.com/qemu/qemu/commit/3d40db0efc22520fa6c399cf73960dced423b048

"This patch thus defines a policy that the #QEMU project will currently not accept contributions where use of #AI code generators is either known, or suspected."

New to FreeBSD? Getting started is easier than you think.

As more people explore FreeBSD beyond servers, we're showing just how simple it is to dive in — even on a MacBook. Whether you're installing from scratch or trying out a virtual machine, FreeBSD offers flexible options to fit your setup.

For a full walkthrough, check out the blog post linked below: https://freebsdfoundation.org/blog/three-ways-to-try-freebsd-in-under-five-minutes/

Planned project for the next few days: Familiarizing myself with FreeBSD/NetBSD and migrating services provided via Proxmox to the chosen BSD host. #Bhyve #NVMM #QEMU

What solutions do Wayland users use for passing keybindings (ex: Alt-Tab) through to a VM being viewed with virt-viewer or remote-viewer in a Wayland WM? X11 had some kind of special hint to tell the WM to pass all keybindings through to the VM's viewer window. Do you just temporarily disable keybindings while viewing a VM? Is it possible to run virt-viewer or remote-viewer in a separate instance of Wayland/wlroots that only displays that windows and passes all keyboard input to it (e.g. the Wayland equivalent of xinit virt-viewer ... -- :1)?

I wonder if it's possible to do "video passthru" (not to be confused with GPU passthru) with libvirt/qemu? Is it possible to send all video data from qemu to an unallocated TTY or possibly an empty X/Wayland session and switch to it using Ctrl+Alt+F8+?

Read all about the Regensburg University (OTH) and my friends there who didnt have a quantum computer so they decided to simulate emulate virtualize one. That way they can provide useful results for software architecture and science of quantum computing. Awesome. #OTHRegensburg #OTHR #regensburg #quantumcomputing #quantummechanics #opensource #linux #kvm #qemu . Thanks to Professor Mauerer, Ralf Ramsauer and their team. Read all about it in the next #linuxmagazin @redaktion !
