Open Source ChromeOS Virtual Machine Software

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.

The open-vm-tools project provides a suite of open source virtualization utilities and drivers to improve the functionality and user experience of virtualization. The project currently runs in guest operating systems under VMware virtualization.

Jasmin is a Java Assembler. It takes ASCII descriptions for Java classes, written in a simple assembler-like syntax. It converts them into binary Java .class class files suitable for loading into a Java Virtual Machine implementation.

This is an x86 emulator written in pure Java based on the Dosbox project. It currently supports running Dosbox's built in DOS and well as booting into Windows 95/98/NT4.

Instructions: After starting this VM, enable the Play Store app, by clicking the Settings -> Apps -> Play Store -> Enable. Then, Launch Play Store App, by clicking the 3 vertical dots icon, at the bottom of desktop. Then download whatever app is needed from the Play Store. Quickly, Cancel any automatic downloads of Play Store app ( itself ), from the notification drawer, as this will prevent it from its future working. Disable the Play Store app, after your other app installs are completed. Increase CPU Count and Memory in VM's Settings, as required, for better performance. If you are very new to virtual machines, then please refer the Wiki Page for its setup instructions, for all major operating systems.

HaLVM is a Haskell-based unikernel system that lets you write entire virtual machines in Haskell and run them directly on a hypervisor, traditionally Xen. Instead of deploying a full operating system, you compile a Haskell program into a tiny image that boots as its own VM, which reduces the attack surface and startup time. The project adapts GHC and the Haskell runtime to a minimal environment, providing the I/O, networking, and memory facilities necessary for standalone services. Its design encourages highly isolated services—each VM does one job—making it attractive for security-sensitive components and research on microservice-style architectures. Developers get to keep Haskell’s strong typing, concurrency abstractions, and functional style while targeting bare virtual hardware. Although device support is intentionally narrow compared to general-purpose OSes, the trade-off is predictability and very small, auditable deployments.

The Mozart Programming System is an open source implementation of the programming language Oz 3. Oz is a multi-paradigm language that supports declarative programming, object-oriented programming, constraint programming, concurrency and distributed programming as part of a coherent whole.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

This VM is created for 2 reasons: 1. Very little initial setup work required to Develop / Test / Deploy a Dynamic Web Application live, within minutes. 2. This system should keep running for Years, without requiring Updates / Breakages. If you are new to Virtual Machines, then please watch the Video below ( taken from my other sample PHP project called teamdocs. You may cleanup this Application from the htdocs home folder link & its corresponding database, after logging into mysql. The mysql root login credentials, sample .mysql_history, sample .bash_history are all kept intact for quick references in the home folder. These files can be edited using the free FileZilla ftp client software. This is also explained in the video below. ) Once setup & running, please ensure that a Backup of the system, is taken regularly, to avoid any issues. These are covered in the video. Google Search helps in finding more about PHP development / troubleshooting.

The Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are imperative, procedural, object-oriented, declarative using nested structures, functional, meta programming and natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, Microcontrollers, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be simple, small and flexible. Ring is distributed as a Free-Open Source project under the MIT License.
