Open Source C Virtualization Software

BitVisor is a tiny hypervisor initially designed for mediating I/O access from a single guest OS. Its implementation is mature enough to run Windows and Linux, and can be used as a generic platform for various research and development projects.

My changes to qemu for legacy free GPU passthrough. Only one adapter can use legacy vga regions at same time. This is an attemp to achieve a qemu gpu passthrough without legacy vga accesses to graphics card. Legacy io accesses to vga registers are replaced through MMIO accesses. Legacy accesses to vga memory are replaced through accesses to plain framebuffer. This avoids vga arbiter problems in linux kernel.

CJKPython is internationalization and localization efforts for Chinese, Japanese and Korean environments on Python.

m23 is a free software distribution system (license: GPL), that installs (via network, starting with partitioning and formatting) and administrates (updates, adds / removes software, adds / removes scripts) clients with Debian, (X/K)Ubuntu and LinuxMint. It is used for deployment of Linux clients in schools, institutions and enterprises. The m23 server is controlled via a web interface. A new m23 client can be installed easily in only three steps. Group functions and mass installation tools make managing a vast number of clients comfortable. The integration of existing clients (with .deb-based distributions) into the system is possible, too. Client backup and server backup are included to avoid data loss. With the integrated virtualisation software, m23 can create and manage virtual m23 clients, that run on real m23 clients or the m23 server. Scripts and software packages (for installation on clients) can be created directly from the m23 web interface.

This project is used to simulate Bluetooth connections over TCP/IP. The server can run under Windows or Linux however Bluetooth devices can only be simulated on Linux for now. May be used to emulate Bluetooth connections between two virtual machines (e.g. VMware) running Linux. (The server would run on the host system in this case.)

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).

FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow

High Availability using Virtualization: Set up two servers (main and backup). The backup should come into action when the main goes down, & should continue the operation that the main was running, exactly from the point of failure, without loss of data.

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 **.

Luvalley is a lightweight type-1 Virtual Machine Monitor (VMM) with novel architecture, to enable any OS to host virtual machines as pure applications by utilizing hardware virtualization extensions such as Intel VT and AMD-V.

Open Source Application Server Appliance based on Open Source GlassFish

A microkernel operating system distribution offering (among other things) very low hardware requirements, full and easy portability and easy-readable source code.

* Model-checking/simulation-checking library for real-time system with dense-time models in C with CRD (Clock-Restriction Diagrams) technology. * Parametric analysis library for linear-hybrid systems in C with HRD (Hybrid-Restriction Diagram) technol

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.

Specter - Abstract Arithmetics Library (AAL) is a library coded in native C which is able to do operations with numbers of virtually unlimited length. Specter is targeting mainly cryptography and big integer maths though.

A hardware supported hypervisor originally built for malware analysis. Features: Linux VM introspection, minimal detectability, small (~150KB), simple, and well documented. Can be used for other purposes. Support for Intel-VT & Windows coming soon.

OpenGL apps running inside a VM use VMGL to obtain graphics hardware acceleration. VMGL supports VMware, Xen PV and HVM, qemu, and KVM VMs; X11-based OS such as Linux, FreeBSD and OpenSolaris; and ATI, Nvidia and Intel GPUs.

Documentation, examples, and reference driver code for the VMware virtual graphics device used by all VMware virtual machines. This project provides the information and code necessary to write both 2D and 3D graphics drivers for this device.

Vassert is a new feature from VMware Workstation. It is promising for developers to enhance code reliablity with less run-time cost. This project is a library to enable vassert usage under Linux guest os.

The project is intended to create a Beowulf cluster using Virtual machines. The application can be used to calibrate and estimate the hardware required to create a Beowulf Cluster.

VirtuoCP is a Virtual private server (VPS) control panel. It is designed to perform VPS operations in a GNU/Linux server having OpenVZ virtualization technology. VirtuoCP is a Free software distributed under GPL license.

Xvisor® is an open-source type-1 hypervisor, which aims at providing a monolithic, light-weight, portable, and flexible virtualization solution. It provides a high performance and low memory foot print virtualization solution for ARMv5, ARMv6, ARMv7a, ARMv7a-ve, ARMv8a, x86_64, and other CPU architectures. The Xvisor source code is highly portable and can be easily ported to most general-purpose 32-bit or 64-bit architectures as long as they have a paged memory management unit (PMMU) and a port of the GNU C compiler (GCC). Xvisor primarily supports Full virtualization hence, supports a wide range of unmodified Guest operating systems. Paravirtualization is optional for Xvisor and will be supported in an architecture independent manner (such as VirtIO PCI/MMIO devices) to ensure no-change in Guest OS for using paravirtualization.

EaseFilter Cloud File System is a Windows virtual file system which was developed with the file system filter driver. The Cloud File System integrates the cloud storage into the on-premise storage, it lets on-premise application access the cloud files transparently, just as they would access on-premise regular files. With the Cloud File SDK, the developers can implement the cloud disaster recovery (Cloud DR) solution, seamlessly integrate your existing applications to the cloud environment without affecting the original data and programs, without any modification of your existing applications. It can help the small to medium size companies to implement the Cloud DR with the lowest cost and minimal disruption to normal operation.

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.
