[AMD Public Use]
Hi Alec,
I am using Ubuntu 20.04.1 with kernel 5.4.0-42.
Hugepage is configured in the grub
$ grep HugePages_ /proc/meminfo
HugePages_Total: 4096
HugePages_Free: 4096
HugePages_Rsvd: 0
HugePages_Surp: 0
In the host, I can manually bind the devices to vfio-pci, but in the container,
it cannot bind the devices to vfio-pci or igb_uio. Please see the logs in the
attached file.
Regards,
Charlie Li

This likely indicates that Trex failed to start properly, possibly pci address
issue or other dpdk related issue.
Can you check/share the trex config and trex log which are located inside the
container at:
/etc/trex_cfg.yaml
/tmp/trex.log
(you can use docker cp or simply docker exec <nfvbench> cat /tmp/trex.log)
Make sure you have your server is set properly to run dpdk (you need huge pages
configured).

Thanks Alec for your help.
Now I can start it but it fails to connect to the server.

I tried to bind the devices to vfio-pci manually but it still cannot connect to
the server.

Hi Charlie,
This is likely due to the file "/tmp/nfvbench/nfvbench.cfg" missing inside the
container.
Can you check the following:
* Check where you stored the nfvbench.cfg file on the host (the
quickstart guide suggests to put the file under $HOME/nfvbench)
* Check that that directory on host is mapped to /tmp/nfvbench in the
container
To verify you can also try to cat that file from inside the container (docker
exec <container name> cat /tmp/nfvbench/nfvbench.cfg)
For further interaction, you can continue on this email thread or you can join
opnfv.slack.com #nfvbench if you prefer.
Thanks
Alec

Hello,
I am new to NFVbench and is following the link below to get started

The NFVbench container is started successfully
