Intel X710 10GbE SFP+ (passthrough) not detected

Dark-Vex

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

    I got the same problem.

    Did you found a solution for that problem ?

    Not yet, I tried to downgrade the firmware but with no luck

    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.
