0-Day Continuous Integration (CI) Test Service from Intel — With so much code contributed to each release, it’s impossible to avoid potential regressions. To eliminate them, you must first find the bugs that cause them, which can be like finding a needle in the proverbial haystack. This is what makes the 0-Day Continuous Integration (CI) Test Service so important. 0-Day delivers comprehensive, automated and continuous integration testing that monitors the Linux mainline and 800+ developer trees for regressions, helping find bugs before they reach the Linux kernel so problems can be fixed before they impact users. Simply put, 0-Day helps ensure Linux kernel quality in a highly complex development environment.
Snowpatch: continuous-integration testing for the kernel — The Linux kernel project lags many others in its use of CI testing for a number of reasons, including a fundamental mismatch with how kernel developers tend to manage their workflows. At linux.conf.au 2019, Russell Currey described a CI system called Snowpatch that, he hopes, will bridge the gap and bring better testing to the kernel development process.

Linux Test Project — Linux Test Project is a joint project started by SGI, OSDL and Bull developed and maintained by IBM, Cisco, Fujitsu, SUSE, Red Hat, Oracle and others.

google/syzkaller — syzkaller is an unsupervised, coverage-guided kernel fuzzer
openQA | Introduction to the heart of openSUSE's automated testing — OpenSUSE is way too versatile for humans to test even the most common configurations. Therefore openQA was introduced and became an indispensable part of the openSUSE development and release processes. openQA is an automated test tool for operating systems. It allows to test the whole installation process of an operating system in a wide range of software and hardware configurations by leveraging qemu. This talk gives an introduction to openQA and explains how openQA works to help understand what it's output means.
OpenQA - Fedora Project Wiki — Fedora uses the openQA automated testing system as a significant part of the release validation testing process, and for testing updates. On this page you can find more information about openQA, how Fedora uses it, and how to install your own instance of openQA so you can try it out and contribute to test development.

This will all be solved eventually but until then I recommend using the 32 bit version of Ubuntu or waiting until the Raspberry Pi 4 support catches up. If you want to run the 64 bit one now anyway it works fine other than the memory limitation.

Our crew walks you through their PCI Passthrough setups that let them run Windows, macOS, and distro-hop all from one Linux machine.

Forget multiple partitions, dual booting, and Hackintoshes; you can do it all with Linux and KVM.

Near-native VM performance doesn't have to be painful. You only need a few prerequisites and a little help.

Special Guest: Alex Kretzschmar.

VFIO tips and tricks: IOMMU Groups, inside and out — Sometimes VFIO users are befuddled that they aren't able to separate devices between host and guest or multiple guests due to IOMMU grouping and revert to using legacy KVM device assignment, or as is the case with may VFIO-VGA users, apply the PCIe ACS override patch to avoid the problem. Let's take a moment to look at what this is really doing.
"Error 43: Driver failed to load" on Nvidia GPUs passed to Windows VMs — Since version 337.88, Nvidia drivers on Windows check if an hypervisor is running and fail if it detects one, which results in an Error 43 in the Windows device manager. Starting with QEMU 2.5.0 and libvirt 1.3.3, the vendor_id for the hypervisor can be spoofed, which is enough to fool the Nvidia drivers into loading anyway.
Mac OS Adds Early Support for VirtIO, Qemu - The Passthrough POST — In a new development uncovered by Qemu developer Gerd Hoffmann, Apple has apparently added early support for VirtIO and framebuffer graphics in a later Mac OS Mojave release.
New and Improved Mac OS Tutorial, Part 1 (The Basics) - The Passthrough POST — Due to certain recent developments, It’s become clear to us that it’s necessary to update and improve our OSX VM guide. A lot’s changed since we wrote it, and rolling in those changes will make the process much more user friendly and accessible to newer VFIO users.
Mac OS VM Guide Part 2 (GPU Passthrough and Tweaks) - The Passthrough POST — We’ve made every attempt to make this as straightforward as possible, but there’s a lot more ground to cover here than in the first part of the guide
UGREEN USB 3.0 Sharing Switch Selector 4 Port 2 Computers Peripheral Switcher Adapter Hub for PC, Printer, Scanner, Mouse, Keyboard with One Button Swapping — This USB Switch 4 Port device allows up to 2 users to share 4 USB 3.0 peripheral devices, such as printer,scanner,mouse,keyboard or usb disk etc without the need to constantly swap cables or set up complicated network sharing software. It's a great for use at home if you have multiple PCs or Macs.
How to setup VFIO GPU passthrough using OVMF and KVM on Arch Linux — This article will detail the steps required to passthrough your GPU to a guest VM which will in our case be a Windows 10 VM used for gaming. Yes, this is the exact same technology made popular by Linus on his LinusTechTips YouTube channel in the seven gamers, one CPU video.

What it takes to run a 32-bit x86 program on a 64-bit x86 Linux system — Suppose that you have a modern 64-bit x86 Linux system (often called an x86_64 environment) and that you want to run an old 32-bit x86 program on it (a plain x86 program). What does this require from the overall system, both the kernel and the rest of the environment?
