Hello!
In case this is of use of anyone, I was able to get VT-d pass through working last night for a DeckLink Mini to a Windows 10 Host. The server is a Dell PowerEdge R710II with a 4c/12t CPU, and 12 Gb RAM. The VM encoded into 1080p30 x.264 without breaking a sweat. This was all done in Proxmox VE.
This has some awesome advantages if my future testing goes. Feel free to ask anything!
