You won't need to wait until I'm on my laptop again. I've been wanting to install VBox on this workstation for a while, but it just hadn't risen to the top of my to-do list yet.
I've done that now, and used it to create a Solus 4.4 Budgie VM.
I had no problems with building it, or with launching it. I haven't bothered to update it yet, but I'll do that next, and let you know if I have any problems with the latest software.
