Hi All,

 

I have an issue with the 2nd 2.5GB NIC on my server. 

 

The story goes...

I've been using Unraid for about 2 years. When I first set it up I flirted with the idea of running opnsense in a vm as my router and abandoned the idea shortly after reading up on the forbidden router. I did however assign a physical NIC to the vm when I was playing about with it. 

 

Fast forward 18 months and a couple of Unraid updates later, I deleted the VM.

 

I then had issues upgrading from 6.12.13 to 6.12.14 when upgrading the server I was getting eth0 interface is down showing -1Mbps, half duplex, mtg 1500 - likely unrelated to this issue.

 

I downgraded back to 6.12.13 and everything went back to normal.

 

I recently upgraded to 7.0.1 (love it btw) but I can't seem to get the 2nd NIC to show up anywhere. When I watch the OS loading log I briefly see an entry "Eth1 doesn't exist"  

 

Really don't know how to attack this one, I've attached diagnostics. Would appreciate someone more knowledgeable giving me a hand, I would like to get this working again for a future project. I suspect it might have been caused by assigning the nic to the VM and deleting the vm before unassigning it? A wild guess.. thank you.

ok so something strange happened just now. I've had no vms for a while, but just turned the service back on, I created a new vm and selected the windows 11 iso to start the install.

 

Turned on the vm and an old Windows 11 vm immediately popped up in the vnc window - that wasn't even listed.

I checked the domains folder and found only the windows 11 folder, I'm wondering if something has happened to the opnsense image not being deleted properly in Unraid or something, but saying that, it wouldn't cause Eth1 doesn't exist on Unraid boot up would it? 

 

I'm really confused, I feel like doing a factory reset would probably solve this, but setting all this up took more time than I currently have.

The other NIC is bound to vfio, so it's not available for Unraid, delete /boot/config/vfio-pci.cfg and reboot, it should then be available.

Thank you very much @JorgeB

i’ll try it and report back. Could you let me know how you discovered that? I’m keen to learn - I have an IT background just not in Linux much.
