Hmm, I disabled the VGA passthrough, and it all seems to work fine, I'm 
going to try passing my GPU
through now that it's installed, but I doubt that it'll work.

I'm using an XFX Radeon 7850 for passthrough, it's reported to work, so 
I think that it's the issues
that I've been having with my AMD FX-6300 processor and IOMMU..

If anybody knows of how to fix these issues, that would be great..
