[SOLVED] How to isolate my Nic's ?

Hello,

 

I have a motherboard with 2 NIC's (1x1gb/s and 1x2.5gb/s)

I added a dual NIC card but I cannot "break" the IOMMU groups.

I followed this video tutorial A little about Passthrough, PCIe, IOMMU Groups and breaking them up

But I can nor enable the PICe ACS override in the VM Manager (when I choose Downstream, I apply, but it stays "disabled"), neither can I add vfio-pci.ids option in the boot parameters (when I click apply, my change disappears).

 

Here are the groups in which my NIC's are:

 

In network settings I only see the NIC's of my motherboards:

 

How can I do ? 

 

Thank you

 

 

EDIT: It was a problem with the key
