PCI Passthrough NIC to VM not selectable

[DorMoordor]

Hi,
I'm trying to pass a NIC to a VM. But if I want to add the Device and select PCI Passthrough I cannot find it.

lspci shows me the following.

So I think I have to use one of the two devices with 01:00.X. If I understood correctly in the GUI it would be the device pci_0000_01_00_X.

But in the List is no such PCI device.

I forgot to mention: I'm using TrueNAS-SCALE-22.02-RC.2

We had this elsewhere, maybe it is regarding IOMMU groups, meaning both 1.xxx NICs are in one group and if you passthrough one, the other would be passed through too, but thats the one used currently. You can pass 4.xxx - maybe try and plug in in the realtek, and then pass both NICs (alls member of IOMMU group) to the VM?

I thought that too, but 4.xxx is the one used for Truenas and both 1.xxx are not used at the Moment and should be passed through.
I want to do what you suggest, this is my goal. But I'm trying since 7 hours and have no solution until now

So I upgraded to TrueNAS-SCALE-22.02.0. Same issue.

I'm not using both NICs of the PCI card (see picture below). I tried to delete both network Interfaces (enp1*), but nothing changes. Does anyone have more suggestion, what I could try?
