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.

umoci is a tool that allows for high-level modification of an Open Container Initiative (OCI) image layout and its tagged images.

Osinfo-db provides the database files for use with the libosinfo library. It provides information about guest operating systems for use with virtualization provisioning tools

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.

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 Python bindings to the libvirt virtualization library.

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.

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.

The virt-manager application is a desktop user interface for managing virtual machines through libvirt. It primarily targets KVM VMs, but also manages Xen and LXC (Linux containers). It presents a summary view of running domains, their live performance and resource utilization statistics.

This package provides a Vagrant plugin that helps you reduce the amount of coffee you drink while waiting for boxes to be provisioned by sharing a common package cache among similar VM instances. Kinda like vagrant-apt_cache or this magical snippet but targeting multiple package managers and Linux distros.

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.

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

Vagrant is the command line utility for managing the lifecycle of virtual machines. Isolate dependencies and their configuration within a single disposable and consistent environment.

Note: Make sure to have ssh and rsync installed — if you use the respective Vagrant functions. This package does not link to any specific implementation of these to allow different clients and to avoid configuration conflicts when running on a `foreign distribution'.

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.

qmpbackup is designed to create and restore full and incremental backups of running QEMU virtual machines via QMP, the QEMU Machine Protocol.

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

The RISC-V Proxy Kernel, pk, is a lightweight application execution environment that can host statically-linked RISC-V ELF binaries. It is designed to support tethered RISC-V implementations with limited I/O capability and thus handles I/O-related system calls by proxying them to a host computer.

This package also contains the Berkeley Boot Loader, bbl, which is a supervisor execution environment for tethered RISC-V systems. It is designed to host the RISC-V Linux port.

Libx86emu is a small library to emulate x86 instructions. The focus here is not a complete emulation but to cover enough for typical firmware blobs. You can

1. intercept any memory access or directly map real memory ranges

2. intercept any i/o access, map real i/o ports, or block any real i/o

3. intercept any interrupt

4. add a hook to run after each instruction

5. recognize a special x86 instruction that can trigger logging

6. use integrated logging

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

This Vagrant plugin enables reloading a Vagrant VM as a provisioning step.

This package provides a GTK+ support for open-vm-tools.

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.

Python-vagrant is a Python module that provides a thin wrapper around the vagrant command line executable, allowing programmatic control of Vagrant virtual machines.
