Hi,

This series implements supports for the uQEMU "-display dbus" support, that
landed earlier this week for 7.0.

By default, libvirt will start a private VM bus (sharing and reusing the
existing "vmstate" VM bus & code).

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.

4 months later, the QEMU bits are now in the last release. This series has certainly bit rot. Could someone give it a review before I attempt rebasing?

thanks
 

thanks
