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

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 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.

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

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

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.

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.

Looking Glass allows the use of a KVM (Kernel-based Virtual Machine) configured for VGA PCI Pass-through without an attached physical monitor, keyboard or mouse. It displays the VM's rendered contents on your main monitor/GPU.

This package provides Python bindings to the libvirt virtualization library.

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.

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

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.

vagrant-spec is a both a specification of how Vagrant and its various components should behave as well as a library of testing helpers that let you write your own unit and acceptance tests for Vagrant.

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

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.

The XenServer guest utilities enable a Xen-based hypervisor, (Citrix XenServer, XCP-NG, etc.) to work with a Xen-enabled Unix-like guest VMs. This allows the guest to share information about its state back to the host, such IP address, memory usage, etc. and allows the host to inform the guest VM about events that change the virtualized hardware, such as hotplugging.

runc is a command line client for running applications packaged according to the Open Container Initiative (OCI) format and is a compliant implementation of the Open Container Initiative specification.

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.

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.

LXCFS is a small FUSE file system written with the intention of making Linux containers feel more like a virtual machine. It started as a side project of LXC but can be used by any run-time.

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.

transient is a wrapper for QEMU allowing the creation of virtual machines with shared folder, ssh, and disk creation support.

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.

virt-what is a program which can be used to detect if the program is running in a virtual machine.

The program prints out a list of "facts" about the virtual machine, derived from heuristics. One fact is printed per line.
