No pf0hpf, no ovs bridge after installation, no virtual function representor set up

Infrastructure & Networking BlueField

I am having an issue, and I need help desperately!!!

My problem is that, after installing the bfb image and the doca host packages, I see no pf0hpf whatsoever. There is no OVS bridge set up automatically, as claimed by the NVIDIA documentation. When I create virtual functions on the host, the representors are not created on the DPU side. This is driving me crazy. My assumption is that a long time ago, I have deleted the ovs bridges. But since then I have reburned the bfb images several times, and it is still not working

Many thanks in advance.

By default, if you use correct doca bfb, ovs had been there already, no need any configuration.

Pls, use below bfb,

I am having the same problem and this solution doesn’t work for me. I’ve tried using installing both DOCA_2.2.1_BSP_4.2.2_Ubuntu_22.04-13.23-09.prod.bfb and DOCA_2.2.0_BSP_4.2.0_Ubuntu_22.04-2.23-07.prod.bfb, neither bring up the pf0hpf interface on the bluefield.

These are the only interfaces that show up:

Hmmm… I downgraded the Bluefield image to DOCA_1.5.2_BSP_3.9.6_Ubuntu_20.04-5.2306-LTS.prod.bfb and the pf0hpf/pf1hpf interfaces appeared.

My ultimate goal is to run the TLS Offload example described in TLS Offload - NVIDIA Docs. Is this possible with DOCA 2.2.x software? It seems like the instructions are broken.

That is really interesting. I will try that out! Thank you!

By the way, what is the host DOCA version that you are using? I am not sure if this is relevant as well.

6

Yes I agree, I have downloaded the latest bfb, and it doesn’t work at all. This needs to be fixed. Without virtual function representor, I cannot do anything interesting!

I’m currently using doca-host-repo-ubuntu2204_2.2.0-0.0.3.2.2.0080.1.23.07.0.5.0.0_amd64.deb. I know there’s a 1.5.2 version for this, but I haven’t found a reason yet to try a downgrade.

8

thanks, I will try that out. I will update the outcome later here. Many thanks!

hmmm, that is confusing, I am using
DOCA_1.5.1_BSP_3.9.3_Ubuntu_20.04-4.2211-LTS.signed

and the after flashing the bfb, the ifconfig -a on the DPU side still looks sth like this:

am I missing any step here?
