First installation TNSR no interface SR-IOV

asolaro

Hi,

I'm trying to evaluate tnsr, but I'm already stuck at the first step.

I tried the installation on a Proxmox server that uses KVM, the VM has the CPU set as host and i gave it two interfaces, one virtio for management to be put in dhcp and the other a VF of a Intel Corporation Ethernet Controller 10-Gigabit X540-AT2.

During the installation i configured the virtio interface in dchp and it takes ip correctly, i leave the VF interface on disabled.
At the end of installation, after login i should find the VF in the dataplane, but show interface returns empty. Then i tried to configure it manually with the following commands:

dataplane dpdk dev 0000:00:10.0 network name WAN
service dataplane restart

But show interface still empty.

How can I solve it?

Thanks for your help

what does "tnsr(config)# dataplane dpdk dev ?" command shows?

I have already tried all the possible combinations between dataplane dpdk iova-mode and dataplane dpdk uio-driver

The host don't showing the VF interface, it has only the virtio that i use for management.

I solved the problem, the NIC was down no-carrier.

Once I had the interface up I was able to configure everything as I wanted.

A positive note to Netgate support who gave me assistance in resolving the problem.
