Kaldek Posted October 14, 2019 Share Posted October 14, 2019 (edited) I have an unraid 6.7 system based off an X99 motherboard and i7-6950X with 64GB of memory. This system has an onboard r8169 ethernet NIC and a PCI-e TP-Link branded e1000 NIC. The PCI-e card is in its own IOMMU group and is used as a sniffer NIC attached to a VM (which runs NtopNG) and the cable is connected to a mirror port off my network switch. The onboard NIC has been configured to be eth0 for...well...forever, and the PCI-e card is eth1. Today, I rebooted and eth0 is now eth1, and of course eth1 is now eth0. I cannot for the life of me work out what the hell is going on. Dmesg of my system is attached. Note this dmesg includes when I switched the cables around and allowed the PCI-e card to operate as eth0 so I can at least use my blimmin' server. I need to FORCE the onboard NIC to *always* be eth0 no matter what. I cannot rely on this renumbering. What happens when it decides to renumber itself again? dmesg.txt Edited October 14, 2019 by Kaldek Quote Link to comment
Kaldek Posted October 14, 2019 Author Share Posted October 14, 2019 Ugh, I'm such an idiot. It's because I booted to GUI mode and I didn't have the "vfio-pci.ids=10ec:8168" after the append command. *Sigh* Quote Link to comment
John_M Posted October 14, 2019 Share Posted October 14, 2019 Don't feel so bad about it. It's an easy mistake to make and this thread might help someone else with the same problem. Quote Link to comment

On the append line of the desired boot mode in syslinux.cfg. I don't pass that particular parameter, but, I do have security mitigations turned off and this is how it alters the 'append' line in syslinux.cfg: Edited October 14, 2019 by Hoopster 1 Quote Link to comment
