Setting up a second GPU passthough

[wmsmckay]

I have setup a GPU passthrough on my Proxmox 7 instance with a GTX 1050 to a windows VM. I just setup a media server and I would like to add a gpu to that vm as well so I can have transcoding but I can't figure out what is wrong as the VM doesn't start up. I am trying to connect a Radeon HD 6670 to an Ubuntu VM. I did all of the setup for the 1050 so I assumed that I wouldn't have to do anything different for the 6670 but I guess not. What step am I missing in order to add a second GPU passthrough to a second VM?

VM start error:
