pbear Posted December 22, 2020 Share Posted December 22, 2020 (edited) 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 Edited December 24, 2020 by pee_bear Quote Link to comment
