    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.

    The LLVM Compiler Infrastructure

    The LLVM Compiler Infrastructure

    Collection of modular and reusable compiler and toolchain technologies

    The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. LLVM began as a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research. Code in the LLVM project is licensed under the "Apache 2.0 License with LLVM exceptions". The LLVM Core libraries provide a modern source- and target-independent optimizer, along with code generation support for many popular CPUs (as well as some less common ones!).

    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.

    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.

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.

    AutomatedLab

    AutomatedLab

    Framework that lets you deploy complex labs on HyperV and Azure

    AutomatedLab is a provisioning solution and framework that lets you deploy complex labs on HyperV and Azure with simple PowerShell scripts. It supports all Windows operating systems from 2008 R2 to 2019, some Linux distributions and various products like AD, Exchange, PKI, IIS, etc. AutomatedLab (AL) enables you to setup test and lab environments on Hyper-v or Azure with multiple products or just a single VM in a very short time. There are only two requirements you need to make sure: You need the DVD ISO images and a Hyper-V host or an Azure subscription. Requires Windows Management Framework 5+ (Windows). Requires Intel VT-x or AMD/V capable CPU, a decent amount of RAM, and low-latency high-throughput storage (No spinning disks please, as there are issues related to them). This solution supports setting up virtual machines with Windows 7, 2008 R2, 8 / 8.1 and 2012 / 2012 R2, 10 / 2016, 2019, and SQL Server 2008, 2008R2, 2012, 2014, 2016, 2017, 2019.

    Bareflank Hypervisor

    Bareflank Hypervisor

    lightweight hypervisor SDK written in C++

    The Bareflank Hypervisor is an open source hypervisor Software Development Toolkit (SDK) for Rust and C++, led by Assured Information Security, Inc. (AIS), that provides the tools needed to rapidly prototype and create your own hypervisor on 64bit versions of Intel and AMD (ARMv8 CPUs, RISC-V and PowerPC also planned). The Bareflank SDK is intended for instructional/research purposes as it only provides enough virtualization support to start/stop a hypervisor. Bareflank can also be used as the foundation to create your own, fully functional hypervisor as it uses the MIT license, and includes 100% unit test coverage and compliance for AUTOSAR. If you are looking for a complete hypervisor (and not an SDK), please see MicroV. If you are looking for a minimal SDK for education or to perform research, this is the project for you. If you are simply looking for a reference hypervisor, please see SimpleVisor.

    Simplify

    Simplify

    Android virtual machine and deobfuscator

    Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

    ievms

    ievms

    Automated installation of the Microsoft IE App Compat virtual machines

    Microsoft provides virtual machine disk images to facilitate website testing in multiple versions of IE, regardless of the host operating system. Unfortunately, setting these virtual machines up without Microsoft's VirtualPC can be extremely difficult. The ievms scripts aim to facilitate that process using VirtualBox on Linux or OS X. With a single command, you can have IE6, IE7, IE8 and IE9 running in separate virtual machines. Install network adapter drivers by opening the drivers CD image in the VM. The IE6 network drivers must be installed upon first boot, or an activation loop will prevent subsequent logins forever. If this happens, restoring to the clean snapshot will reset the activation lock. The VHD archives are massive and can take hours or tens of minutes to download, depending on the speed of your internet connection. You might want to start the install and then go catch a movie, or maybe dinner, or both.
