Unfortunately I don't seem to have access to the latest images and this happening only when booting the ISO makes it hard(er) to grab data. I did finally succeed by using "virsh dump --memory-only <domain> <file>" and then "sudo strings <file>|less". And it looks like the qxl drm driver is crashing. I put the data here for reference but if you could do the same with an iso containing the 4.13 kernel, that would be great.
