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.

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.

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

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.

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

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

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.

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.

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 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.

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.

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.

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

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.

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.

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

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.

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.

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.

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

Bitmask, by LEAP, is an application to provide easy and secure encrypted communication with a VPN. It allows you to select from a variety of trusted service provider all from one app. Current providers include Riseup Networks and The Calyx Institute, where the former is default.
