Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux. The library aims at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

QEMU is a generic machine emulator and virtualizer.

When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine---e.g., your own PC. By using dynamic translation, it achieves very good performance.

When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.

The agent gathers some guest information, and writes them to xenstore so tooling in dom0 can read it. The default behavior is to be compatible with the XAPI toolstack as currently used in XCP-ng and Citrix Hypervisor/Xenserver, and thus roughly follow what xe-guest-utilities is doing.

libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, creating guests, P2V, V2V, performing backups, cloning VMs, building VMs, formatting disks, resizing disks, and much more.

This package provides a guest OS definition for Ganeti. It installs Debian or a derivative using debootstrap.

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.

This package provides a self-contained library for reading and writing Windows Registry "hive" binary files. Unlike many other tools in this area, it doesn't use the textual .REG format for output, because parsing that is as much trouble as parsing the original binary format. Instead it makes the file available through a C API, or through a separate program to export the hive as XML.

Spike, the RISC-V ISA Simulator, implements a functional model of one or more RISC-V harts.

This is a Vagrant plugin that adds a Libvirt provider to Vagrant, allowing Vagrant to control and provision machines via the Libvirt toolkit.

This package provides the Xen Virtual Machine Monitor which is a hypervisor.

This package contains a set of tools to assist administrators and developers in managing the database.

emu.qmp is a QEMU Monitor Protocol (QMP) library written in Python. It is used to send QMP messages to running QEMU emulators. It can be used to communicate with QEMU emulators, the QEMU Guest Agent (QGA), the QEMU Storage Daemon (QSD), or any other utility or application that speaks QMP.

This package provides Python bindings to the libvirt virtualization library.

libosinfo is a GObject based library API for managing information about operating systems, hypervisors and the (virtual) hardware devices they can support. It includes a database containing device metadata and provides APIs to match/identify optimal devices for deploying an operating system on a hypervisor. Via GObject Introspection, the API is available in all common programming languages. Vala bindings are also provided.

This package provides a guest OS definition for Ganeti that uses Guix to build virtual machines.

Ganeti is a virtual machine management tool built on top of existing virtualization technologies such as Xen or KVM. Ganeti controls:

• Disk creation management;

• Operating system installation for instances (in co-operation with OS-specific install scripts); and

• Startup, shutdown, and failover between physical systems.

Ganeti is designed to facilitate cluster management of virtual servers and to provide fast and simple recovery after physical failures, using commodity hardware.

This plugin creates an Ansible inventory file containing the created virtual machines and the respective ssh-parameters.

open-vm-tools is a set of services and modules that enable several features in VMware products for better management of, and seamless user interactions with, guests.

open-vm-tools enables the following features in VMware products:

• The ability to perform virtual machine power operations gracefully.

• Execution of VMware provided or user configured scripts in guests during various power operations.

• The ability to run programs, commands and file system operation in guests to enhance guest automation.

• Authentication for guest operations.

• Periodic collection of network, disk, and memory usage information from the guest.

• Generation of heartbeat from guests to hosts so VMware's HA solution can determine guests' availability.

• Clock synchronization between guests and hosts or client desktops.

• Quiescing guest file systems to allow hosts to capture file-system-consistent guest snapshots.

• Execution of pre-freeze and post-thaw scripts while quiescing guest file systems.

• The ability to customize guest operating systems immediately after powering on virtual machines.

• Enabling shared folders between host and guest file systems on VMware Workstation and VMware Fusion.

• Copying and pasting text, graphics, and files between guests and hosts or client desktops.

libvirt-glib wraps the libvirt library to provide a high-level object-oriented API better suited for glib-based applications, via three libraries:

1. libvirt-glib - GLib main loop integration & misc helper APIs

2. libvirt-gconfig - GObjects for manipulating libvirt XML documents

3. libvirt-gobject - GObjects for managing libvirt objects

skopeo is a command line utility providing various operations with container images and container image registries. It can:

1. Copy container images between various containers image stores, converting them as necessary.

2. Convert a Docker schema 2 or schema 1 container image to an OCI image.

3. Inspect a repository on a container registry without needlessly pulling the image.

4. Sign and verify container images.

5. Delete container images from a remote container registry.

RVVM is a RISC-V CPU and system software implementation written in C. It supports the entire RV64GC ISA, and it passes compliance tests for both RV64 and RV32. OpenSBI, U-Boot, and custom firmwares boot and execute properly. It is capable of running Linux, FreeBSD, OpenBSD, Haiku, and other OSes. Furthermore, it emulates a variety of hardware and peripherals.

Bochs is a highly portable IA-32 (x86) PC emulator written in C++. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Bochs can be compiled to emulate many different x86 CPUs, from early 386 to the most recent x86-64 Intel and AMD processors. Bochs is capable of running most operating systems inside the emulation including GNU/Linux, DOS or Microsoft Windows.
