Threadripper 1950X + Vega 64 + KVM Success! One issue though...

Got High Sierra working on my Threadripper 1950X and Vega 64 build using GPU passthrough through KVM.

It runs fantastic, I just am running into one issue - when I reboot the machine or shut down and start it up again, it gets stuck in some kind of boot loop. In order to fix it, I have to power down the host completely and then run the VM again.

I have another VM running Windows 10 that does not have this issue with the Vega. I can restart it as many times as I want. Interestingly though, when I power down the OSX VM I can't even boot my Windows VM with the Vega until after I power cycle the host too. So it's like it isn't de-initializing the card properly or something.

Let me know if you want me to post my libvirt/qemu XML config. It took some trial and error getting this working, none of the guides I found worked right out of the box. Also I updated HS to the latest version before using the graphics card.
