This write up details my experiences getting PCI passthrough working through Ubuntu 18.04 to Windows 10 using OVMF+VFIO and libvirt. While this document shouldn’t be considered a comprehensive guide, it will cover what I needed to do to get this working (mainly so I can set it back up again if I ever need to), while also covering a few tips and tricks I’ve learned along the way.
