Open Source Unix Shell 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.

Manages a pool of zones that normal users can use. Zones (OpenSolaris containers) are efficiently cloned from a base zone so that building up and tearing down a devzone is fast (on the order of seconds).

Jelatine is a Java virtual machine implementing the Connected Limited Device Configuration of the Java 2 Micro Edition body of standards. It also includes its own CLDC-oriented classpath.

LXCF (LXC Facility) is a tool that generates full OS environment as LXC virtual environment. http://lxcf.sourceforge.jp/index.html.en - It is based on libvirt-lxc - It can generate containers in a short time (in a few minutes each even if it is long). - It can manage a lot of containers. - It supports dynamic resource control of containers. - To use containers for a long term (a few years or more), you can update software on each container from the host. LXCF currently supports **Ubuntu 14.04, Ubuntu 14.10, Fedora 21, Fedora 20 , Fedora 19, CentOS 7 and Red Hat Enterprise Linux 7 **.

Open Source Application Server Appliance based on Open Source GlassFish

OpenSpace 2010 is an free and opensource developpement environment, wich include a sysadmin-targeted module, and a embedded developpement module. Developpers welcome.

Pools of Virtual Boxes (POVB) aims to make it easy to deploy Linux Condor pools on Windows based machines using Virtual Box virtual machines.

A slightly modified base package Slackware image suitable for VM performance testing. Project Goals: Development of production testing protocols Base Image Base +Apache Base + MySQL Base + node.js Base + AoE Standard Full Slackware Current VM image The goal of the Slackless project is really two-fold. To provide high quality virtual images of the original Slackware operating system suitable for use and testing in virtual environments in an effort to introduce users new to Slackware to the advantages of the K.I.S.S. development philosophy. It's longer range goal is to produce a procedure for producing minimal functional server images for use in production environments. The goal is to minimize the image size and resource consumption while maintaining the stability and functionality that makes Slackware famous in an effort to provide implementers of virtual environments and option that allows them to install more server images on existing hardware platforms.

eXtendBus is a device sharing mechanism for Virtualization Platform, specially designed for Xen hypervisor. eXtendBus attempts to modify Xen’s architectural features and combine it with extended device driver architecture.
