Update:
Thank you Zir Blazer and Anthanasios Tasoglou I was able to get it working today in qemu with the following that I cobbled together from <http://turlucode.com/qemu-kvm-on-arch-linux-guide> and right here <https://www.redhat.com/archives/vfio-users/2016-May/msg00010.html> Tomorrow I will try to figure out why it is so slow. Assuming I can get it, I will then try and convert it to domain.xml afterward and post the results here in case someone else could use them. I'm sure it is me, but it's crazy how much more difficult gpu passthrough from linux host to linux guest has been to achieve than linux host to mac guest.
