    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.

    AtomVM

    AtomVM

    Tiny Erlang VM

    Brings Erlang, Elixir and other functional languages to really small systems. AtomVM implements from scratch a minimal Erlang VM that supports a subset of ErlangVM features and that is able to run unmodified BEAM binaries on really small systems like MCUs. There is much more information, including a more complete "Getting Started Guide," extensive documentation, examples, and contact information available on the AtomVM project website. AtomVM aims to be easily portable to new platforms with a minimum effort, so additional platforms might be supported in a near future. AtomVM is still in its early stages, but it can run simple applications similar to those available in examples and tests. This basically means that an instruction has not been implemented yet, or that an outdated version has been used. Please, make sure to always run AtomVM using latest version.

    Byte Buddy

    Byte Buddy

    Runtime code generation for the Java virtual machine

    Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a Java application and without the help of a compiler. Other than the code generation utilities that ship with the Java Class Library, Byte Buddy allows the creation of arbitrary classes and is not limited to implementing interfaces for the creation of runtime proxies. Furthermore, Byte Buddy offers a convenient API for changing classes either manually, using a Java agent or during a build. In order to use Byte Buddy, one does not require an understanding of Java byte code or the class file format. In contrast, Byte Buddy's API aims for code that is concise and easy to understand for everybody. Nevertheless, Byte Buddy remains fully customizable down to the possibility of defining custom byte code. Furthermore, the API was designed to be as non-intrusive as possible and as a result, Byte Buddy does not leave any trace in the classes that were created by it.

    JPHP - an implementation of PHP on Java VM

    JPPM is a packager manager for JPHP like npm or composer. JPPM will help you to build and run jphp applications or write new packages. JPHP is a new implementation for PHP which uses the Java VM. It supports many features of the PHP language (7.1+). How does it work? JPHP is a compiler like javac, it compiles PHP sources to JVM bytecode and then can execute the result on the Java VM. We develop a new IDE for beginners like Game Maker or Scirra Construct. It's based on JPHP, JavaFX, Java 8, and Gradle, and allows to creation of desktop games and apps for Linux, Windows, and Mac (maybe Android and other platforms in the future). JPHP is not a replacement for the Zend PHP engine or Facebook HHVM. We don’t plan to implement the zend runtime libraries (e.g. Curl, PRCE, etc.) for JPHP. PHP 7.1+ (and many language features from PHP 7.2, 7.3, 7.4). JIT (~2.5x faster PHP 5.6, ~1.1x faster PHP 7.0, ~13% slower than PHP 7.4, bench). Using java libraries and classes in PHP code.

    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.

    VM Migration Assistant

    VM Migration Assistant

    Virtual Disk Convert Between VMDK,VHD(X),VDI,QCOW/QCOW2,RAW(IMG)

    VM Migration Assistant is a free tool for cloning and transforming VMs from one format to another, as well as converting physical machines into virtual ones. It is utilized when migration or hypervisor switch is required. Compared to the typical converters built into hypervisors, it offers bi-directional conversion between all the major VM disk formats: VMDK(VM, VirtualBox), VHD/VHDX(Hyper-V), QCOW/QCOW2(KVM, Xen), VDI(VirtualBox) and raw binary image(KVM). VM Migration Assistant has numerous competitive gains over converters built into hypervisors(in plan). First, it supports bi-directional VM conversion between different hypervisors. For saving time during migration and hypervisor switch, V2V Converter / P2V Migrator enables to convert VMs directly from one hypervisor storage to another, without creating an extra VM disk copy. On top of that, the utility ensures a safe P2V migration by using a VSS snapshot of the source machine to ensure data consistency.
