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.

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

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.

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.

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

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

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

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.

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.

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.

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.

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.

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.

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 is an internal helper for vagrant-spec. Don't use it.

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.

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

V is a systems programming language. It provides memory safety and thread safety guarantees with minimal abstraction.

This package provides LibVNCServer and LibVNCClient. These are cross-platform C libraries that allow you to easily implement VNC server or client functionality in your program.

x11vnc allows one to view and interact with real remote X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer.

Remmina is a client to use other desktops remotely. RDP, VNC, SPICE, NX, XDMCP, SSH and EXEC network protocols are supported.

TurboVNC is a high-speed version of VNC derived from TightVNC, with which it remains compatible. It contains a variant of Tight encoding that is tuned to maximize performance for image-intensive applications (such as VirtualGL, video applications, and image editors) while still providing excellent performance for other types of applications. Some of its unique features are:

• a user-facing vncserver command;

• the ability to capture keyboard keys even when not in full screen mode;

• a full screen mode that is compatible with ratpoison*

*Although due to a quirk in Java, you'll want to set the _JAVA_AWT_WM_NONREPARENTING environment variable when using it with ratpoison.

This is a VNC server for wlroots-based Wayland compositors. It attaches to a running Wayland session, creates virtual input devices, and exposes a single display via the RFB protocol. The Wayland session may be a headless one, so it is also possible to run wayvnc without a physical display attached.

NeatVNC is a lightweight VNC server library, supporting authentication, SSH tunneling, and ZRLE or Tight encoding.
