QEMU D-Bus display experiment

Introduction

WIP Rust crates to interact with a -display dbus QEMU. The development branch is currently: https://gitlab.com/marcandre.lureau/qemu/-/tree/dbus

See also the QEMU mailing list for progress.

Most dependencies are released, but notably zbus 2.0 is still in beta. RDW and VTE4 widgets are also unreleased at this stage.

Features

Depending on what the VM exposes & supports, various interfaces are implemented:

• display, with optional DMABUF sharing
• display resize
• keyboard & mouse
• serial terminals
• QMP/HMP monitors
• audio playback & recording
• USB device redirection
• clipboard sharing

Project organization

qemu-display

This crate provides simple D-Bus interfaces through zbus, and some basic abstractions.

qemu-rdw

This crate aims to provide Gtk+ 4 widget for a QEMU display, as well as dialogs/widgets for USB redirection and other options or features.

Currently it's a demo app (run by default with cargo run).

It is also based on a WIP crate "RDW" (Remote display/desktop widget) to provide a base widget for various remote display solutions (VNC, RDP, Spice etc).

qemu-vnc

A simple VNC server implementation.

qemu-vte

A standalone VTE/Gtk+ 4 client, which should eventually be a consumable crate or integrated with qemu-rdw.
