I have no idea about your virtualization setup / hypervisor but with kvm, there are a few things required. Make sure you have configured the following:

• not using any other display -vga none -nographic
• host CPU type -cpu host (other cpu flags might be necessary to get good performance, e.g. hv_passthough)
• use q35 machine type -machine type=pc-q35-8.1 (or similar)
• VF device like this -device vfio-pci,host=0000:00:02.1,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0 (or similar)

In Proxmox make sure to use pcie and primary gpu options for the passthrough.

I had the same issue. I tried so many combinations and finally managed to get my setup working. Here are the 2 things I did:

1. add <vendor_id state='on' value='GenuineIntel'/> using virsh edit
2. remove the line <feature policy='disable' name='hypervisor'/> from <cpu> section

It all works smoothly now and there's NO error code 43 on my windows guest.

My setup: i7 14700K Fedora 40
