I have two identical GPU’s and I want to pass one to a Linux VM with KVM/QEMU and Virt-Manager, but I’m stuck at picking device ID from lspci -nn. The problem is that both GPUs have the same ID. I found old thread about this problem, but it’s 7 eyars old: 15.04 - PCI GPUs have the same device ids. Why? - Ask Ubuntu

Is this problem solved with today’s tech? How device id’s should be defined in GRUB in that case?

Wendell’s guide that he posted a while ago covers it. You’ve got to use device addresses instead of device IDs.
