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.

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.

Aglais XQVM is a Rust implementation of the Quip Network’s quantum virtual machine, designed to simulate or execute quantum-inspired computation within a blockchain or distributed system context. The project focuses on providing a performant and low-level execution environment that can handle specialized computational workloads associated with quantum algorithms or hybrid systems. Built in Rust, it emphasizes memory safety, performance, and deterministic execution, which are critical for distributed environments. It integrates with the broader Quip ecosystem, allowing it to function as part of a larger protocol stack that includes blockchain infrastructure and node management tools. The virtual machine abstraction enables developers to define and execute computational logic in a controlled environment, potentially bridging classical and quantum paradigms. Its design suggests use cases in advanced computation, cryptography, or experimental distributed systems.

xq-py is a Python implementation of the Quip Network’s quantum virtual machine, offering a more accessible and flexible alternative to the Rust-based version for experimentation and rapid development. It is designed to provide similar functionality to xq-rs while prioritizing ease of use, readability, and integration with Python-based data science and research tools. The project enables developers to simulate or prototype quantum-inspired computations without needing to work at a lower systems level. It integrates into the broader Quip ecosystem, allowing interoperability with other components such as blockchain nodes and management tools. Python’s dynamic nature makes it suitable for testing new algorithms, educational purposes, and exploratory research. The implementation likely sacrifices some performance compared to Rust but gains significant flexibility and ease of iteration.

URBI: Universal Robotic Body Interface. URBI is a scripted command language used to control robots (AIBO, pioneer,...). It is a robot-independant API based on a client/server architecture. Liburbi C++/Java/Matlab are available here. Forum available at ht

GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.

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.
