Hi,
This series implements supports for the upcoming QEMU "-display dbus" support.
Development is still in progress, but I hope to land the QEMU support early in
6.3 (last version posted:
https://patchew.org/QEMU/20211009210838.2219430-1-marcandre.lureau@redhat...).
By default, libvirt will start a private VM bus (sharing and reusing the
existing "vmstate" code). A client will need the address of the bus and access
to it. Since D-Bus addresses are not URIs unfortunately, I am not sure yet what
should "virsh domdisplay" return.
The feature set should cover the needs to replace Spice as local client of choice,
including 3daccel/dmabuf, audio, clipboard sharing, usb redirection, and arbitrary
chardev/channels (for serial etc).
The test Gtk4 client is also in progress, currently in development at
https://gitlab.com/marcandre.lureau/qemu-display/. A few dependencies, such as
zbus, require an upcoming release. virt-viewer & boxes will need a port to Gtk4
to make use of the shared widget.
Comments welcome, as we can still adjust the QEMU side etc.
thanks
