Intel X710 10GbE SFP+ (passthrough) not detected

Hello,

I have a Minisforum MS-01 which have two Intel 2.5GbE and two Intel x710 SFP+.

I'm using Proxmox and I did a PCIe passthrough of one x710 interface (tick/untick pass all feature doesn't matter) to Sophos XG v20 Virtual Machine. By doing an lspci, the PCI device is detected as 8086:1572 but Sophos is not loading the i40e kernel driver:

The i40e driver seems to be the right by looking at it with strings command:

There is a way to force the load of this kernel module? (insmod command is not there)

Thank you,

Daniele

Hello Dark-Vex ,

Thank you for reaching out to the community, please refer the supported third-party transceivers/SFPs compatibility list. There might be many that may or may not work, but this are the tested and approved ones. Additionally for the knowledge you can also refer - VLAN limitations based on chipsets on network modules.

Thanks & Regards,

Thank you Vivek, I have a compatible transceiver but here the problem is the NIC driver not being loaded/detected at all ("ip a sh" doesn't show it) by Sophos XG.

I suspect I need to downgrade (as per Intel Doc) the NIC Firmware to version 7.20 (currently there is 9.20) since the Intel driver for kernel 4.19 included in Sophos XG seems to be old (2.10.19.82), I hope the downgrade will not brick the NIC.

I got the same problem.

Did you found a solution for that problem ?

It‘s strange, but if you use the software-installer instead the kvm-image, the x710 will be usable in the vm.

You're right, I tried right now with software installer (SW-20.0.0_GA-222) instead of kvm image and I confirm that x710 nic is usable in the vm.

I guess at this point that the kvm image only enables nic drivers that can be emulated by kvm. I need to give up with my initial idea of provisioning/do an unattended install of this VM via Terraform

Maybe the problem is fixed in the newest kvm-image v20-MR-1.

You can install one VM with the intial setup and clone the VM.
