PCI/GPU Passthrough - QEMU/KVM shows wrong GPU

Hey,
I am trying to passthrough my 1070ti. I followed these instructions and I guess I was successful isolating the 1070ti.
But when I am in QEMU/KVM and I try to passthrough the 1070ti it only shows me my GT 710B and I just can't figure out what I did wrong or what I missed.

Does someone know how this can happen and how I can fix this?

Thx in advance!

iommu script + groups
QEMU/KVM only shows GT 710B

post lspci -k , dmesg and /etc/modprobe.d/vfio.conf .

Also the output of the script at Ensuring that the groups are valid

Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: PCI/GPU Passthrough - QEMU/KVM shows wrong GPU

Okay, so I did it all over again and now it works. I added the GPU via "add hardware" then I booted up the VM, while having a 2nd monitor plugged into the GPU that was passed through. QEMU/KVM says the VM is running but the 2nd monitor doesn't get a signal hmm
