    Quickemu

    Quickemu

    Quickly create and run optimized Windows, macOS and Linux

    Quickly create and run optimized Windows, macOS, and Linux virtual machines. Quickemu is a wrapper for the excellent QEMU that automatically "does the right thing" when creating virtual machines. No requirement for exhaustive configuration options. You decide what operating system you want to run and Quickemu takes care of the rest. The original objective of the project was to enable quick testing of Linux distributions where the virtual machines and their configuration can be stored anywhere (such as external USB storage or your home directory) and no elevated permissions are required to run the virtual machines.

    Crosvm

    Crosvm

    The Chrome OS Virtual Machine Monitor

    crosvm (ChromeOS Virtual Machine Monitor) is a secure, lightweight virtual machine monitor built on top of the Linux KVM hypervisor. Developed for ChromeOS, it is designed to isolate and execute Linux and Android guests efficiently while maintaining strong security boundaries. Unlike general-purpose emulators like QEMU, crosvm avoids full hardware emulation and focuses on modern paravirtualized I/O using the virtio standard, reducing complexity and attack surface. Written in Rust, it emphasizes memory safety and modularity, allowing sandboxed device emulation with fine-grained privilege separation. crosvm underpins several ChromeOS subsystems, including Android Runtime for Chrome (ARCVM) and Crostini Linux containers, enabling rich application compatibility within a tightly controlled environment.

    Windows (Dockur)

    Windows (Dockur)

    Windows inside a Docker container

    This project makes it surprisingly easy to run a Windows environment inside a Docker container by using a QEMU-based virtual machine under the hood. It provides a turnkey image and a simple set of environment variables so you can select Windows editions, control disk persistence, and access the VM via a web-based VNC console or similar remote viewers. Because the VM is wrapped in Docker, you can treat Windows as a disposable, repeatable service: create, snapshot with volumes, tear down, and rebuild with consistent results. The setup bundles sensible defaults for UEFI/OVMF firmware, virtio devices, and automated first-boot behavior to streamline installation. It’s handy for demos, testing, or hosted tooling that truly requires Windows but where you still want container-style workflows and orchestration.

    OpenJ9

    OpenJ9

    A Java Virtual Machine for OpenJDK

    A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR and combines with the Extensions for OpenJDK for OpenJ9 repo. We're not sure which route you might have taken on your way here, but we're really pleased to see you! If you came directly from our website, you've probably already learned a lot about Eclipse OpenJ9 and how it fits into the OpenJDK ecosystem. Eclipse OpenJ9 is an independent implementation of a Java Virtual Machine. "Independent implementation" means it was built using the Java Virtual Machine specification without using any code from any other Java Virtual Machine. The OpenJ9 JVM combines with the Java Class libraries from OpenJDK to create a complete JDK tuned for footprint, performance, and reliability that is well suited for cloud deployments. The original source contribution to OpenJ9 came from the IBM "J9" JVM which has been used in production by thousands of Java applications.

    MoarVM

    MoarVM

    A runtime built for the 6model object system

    Short for "Metamodel On A Runtime", MoarVM is a modern virtual machine built for the Rakudo Perl 6 compiler and the NQP Compiler Toolchain. MoarVM is used by the majority of Perl 6 programmers. Highlights include: Great Unicode support, with strings represented at grapheme level, dynamic analysis of running code to identify hot functions and loops, and perform a range of optimizations, including type specialization and inlining, support for threads, a range of concurrency control constructs, and asynchronous sockets, timers, processes, and more, generational, parallel, garbage collection, support for numerous language features, including first class functions, exceptions, continuations, runtime loading of code, big integers and interfacing with native libraries. MoarVM provides very little directly - and that's a good thing. It is not tied to a particular way of doing inheritance, roles, mixins, method resolution, type-checking, and so forth.

    macOS Simple KVM

    macOS Simple KVM

    Tools to set up a quick macOS VM in QEMU, accelerated by KVM

    macOS-Simple-KVM is a project that provides scripts and configuration files to easily set up and run macOS in a virtual machine using QEMU and KVM. It simplifies what is typically a complex process by offering a straightforward approach to creating a macOS VM on Linux systems with hardware virtualization support. The repository includes tools for preparing installation media, configuring virtual hardware, and managing VM launch scripts. By using KVM acceleration, the virtual machine runs with near-native performance, making it useful for testing, development, or personal experimentation. The project also supports GPU passthrough and other advanced configurations for users who want a more optimized macOS VM environment. While primarily intended for educational and testing purposes, it demonstrates how macOS can be virtualized outside of Apple hardware.

    macOS (Dockur)

    macOS inside a Docker container

    dockur/macos packages a macOS virtual machine inside a Docker container using QEMU/KVM, making it easy to spin up a macOS environment on a Linux host. It provides sensible defaults for firmware, disk, and devices, plus a browser-accessible VNC console so you can complete installation and interact with the desktop remotely. Typical inputs—like environment variables and mounted volumes—control edition choice, storage persistence, and resource sizing, which makes runs repeatable and disposable. Because it’s containerized, you can script lifecycle operations, snapshot state via volumes, and integrate the VM into CI or demo setups without a traditional hypervisor UI. Performance depends on host capabilities and whether hardware acceleration is available, but for light GUI tasks, tooling, or sandboxing, it’s surprisingly practical. Users should bring their own valid media and licenses, and be mindful of platform terms and host resource limits.

    Boot2Docker

    Boot2Docker

    Linux distribution made specifically to run Docker containers

    Boot2Docker is a lightweight Linux distribution made specifically to run Docker containers. It runs completely from RAM, is a ~45MB download and boots quickly. Boot2Docker is designed and tuned for development. Using it for any kind of production workloads is highly discouraged. Installation should be performed via Docker Toolbox which installs Docker Machine, the Boot2Docker VM, and other necessary tools. Boot2Docker is used via Docker Machine (installed as part of Docker Toolbox) which leverages VirtualBox's VBoxManage to initialise, start, stop and delete the VM right from the command line. Docker Machine auto logs in using the generated SSH key, but if you want to SSH into the machine manually (or you're not using a Docker Machine managed VM), you can do so. Boot2docker uses Tiny Core Linux, which runs from RAM and so does not persist filesystem changes by default.

    macintosh.js

    macintosh.js

    A virtual Apple Macintosh with System 8, running in Electron

    This is Mac OS 8, running in an Electron app pretending to be a 1991 Macintosh Quadra. It works on macOS, Windows, and Linux. Bear in mind that this is written entirely in JavaScript, so please adjust your expectations. The virtual machine is emulating a 1991 Macintosh Quadra 900 with a Motorola CPU, which Apple used before switching to the PowerPC architecture (Apple/IBM/Motorola) in the mid 1990s. You'll find various games and demos preinstalled, thanks to an old MacWorld Demo CD from 1997. Namely, Oregon Trail, Duke Nukem 3D, Civilization II, Alley 19 Bowling, Damage Incorporated, and Dungeons & Dragons. There are also various apps and trials preinstalled, including Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, the Apple Web Page Construction Kit, and more.
