To migrate #FreeBSD guest VMs from #Hyper-V to #libvirt/#KVM:
* Convert to .qcow2 from .vhdx at host, using #Cloudbase.it #qemu-img.exe.
On import:
* Choose FreeBSD 14.2 as OS.
* Choose Q35 as chipset.
* Choose BIOS.
* Import disk image as #VirtIO disk; change to SCSI.
* Add missing virtio-scsi controller.
* Apply "stateless" #EFI <os> from libvirt docs, to enable EFI non-secure boot without XML schema errors.
* Boot the FreeBSD guest.
* Edit /etc/rc.conf to use #vtnet(4), not hn(4).

– the bug is reproducible without the desktop script.

Visit us until the 23rd of January at Booth: W24-9 (1F of West Hall) to discuss how to accelerate your Automotive Development with Linaro.

Getting started with a cool new project: building my own minimalist Linux OS for x86_64 using Buildroot! 🛠️

Just finished the full cross-compilation with the pc_x86_64_bios_defconfig. The resulting tiny system is up and running in QEMU.

Excited to spend the next few days exploring Buildroot's potential, from custom kernels to package management. Time to dig into the embedded world! 🚀

I figured I'd dump this into the void, but has anyone out there successfully done 3d accelerated virtio graphics with a NixOS host?

At EdgeTech 2025, Linaro will present how VirtIO innovation is transforming connectivity across automotive and mobile systems.

Lina Iyer will share how Linaro drives standardization in the Arm ecosystem, contributes to open-source projects like Linux, QEMU, and Android, and advances Virtio-msg to enable faster, more reliable communication for next-generation vehicles.

Join the conversation on the 19/11 at 📍 L1-05

@joeress another one where it was useful was generating a cut down test case for #latex. I was diagnosing a problem with the #virtio specs caused by a regression in htlatex and #gemini was able to generate a nice concise reproducer much faster than I could have.

We got a bunch of security reports for #qemu recently: https://gitlab.com/sculizhenghao. Fortunately these were not slop reports and having test cases with the reports was very useful.

So I was curious about VirtioFS today and decided to satisfy that curiosity with the Help of Gemini DeepResearch. The Resulting document was an interesting read. It looks like the Tool manages not to Hallucinate as it has direct sources. The Part that VirtioFS is basically FUSE was new to me. When I finished reading it I thought, maybe some people might like this read aswell.

So … while this is obviously nice for virtualized gaming, what about video decode/encode acceleration?

Is there a way to give a #Linux guest access to the host #GPU's video codec acceleration without GPU passthrough?

Just like it's possible to pass /dev/dri into a container, can I do a similar thing with a #QEMU / #KVM virtual machine?
