You could ask the vendor if they support running it in KVM/QEMU, and what the requirement would be. There are also software vendors who build (undocumented) checks into their software to disable running it on virtual hardware, sometimes because of licensing, sometimes because of support.
Although you pass through 1 device, there still is a virtualization layer in between Windows and the actual (rest of the) hardware. I have little experience with actual gpu pass through, but this is a requirement so that proxmox doesn´t interfere with the gpu that's passed through.Īlso you should double check if al the other hints and tips in the wiki article have been met.Ī Windows VM might seem the same as native but it's still a VM. Did you make sure the graphics driver is blacklisted in the proxmox host?
