FWIW, I get my images from here


which is linked to from the Fedora wiki


the stage4 there is quite old (April, 2018), is yours newer?  I'm having some

what's going on.

Great!  I've yet to figure out how to get all the PCI stuff working, but I was 
trying to go with a virgl-based GPU which I suspect is broken for other 
reasons.  What sort of devices did you attach?
