I'm working on a kind of "troubleshooting log" option for gnome-boxes which wants to record all these kinds of data so that a helpdesk or a developer can help figuring out a problem with a guest. Knowing if a qxl driver is in use is an important piece of information. Additionally it would be very nice if the driver could report a version string that I could query (same for virtio driver, etc).
