I think there is a bug in that new piece of code, let me check with the person 
who wrote it.
In the meantime if you want a workaround, you could go ahead and remove that 
whole if block (in container, edit /nfvbench/nfvbench/nfvbench.py L169) - it 
can be safely removed.

Thanks
  Alec

Since you are using only 1 external chain, you only need 1 entry in each list.
You also probably will need more than 1 core for TRex.

Hi Alec,


thank you for information. I have deployed it successfully.

Not quite sure about what you mean by “deployed it successfully”. Did you 
launch the VM directly using libvirt and did you manage to pass the right 
config file?


I have one other question, how can I configure nfvbench to work in L2 mode 
without gateway IP settings( DUT put an L2 loop on the end/testPMD mac forward)
ip_addrs: ['16.0.0.0/24', '48.0.0.0/24']
tg_gateway_ip_addrs: ['192.168.0.2', '192.168.2.2']
gateway_ip_addrs: ['192.168.0.12', '192.168.2.12']

where I configure destination MAC


like in trex
port_limit: 2
  version: 2
  interfaces: ['03:00.0', '03:00.1']
  port_info:
      - dest_mac: fa:16:3e:c5:0b:22
        src_mac:  24:8a:07:8e:d3:14
      - dest_mac: fa:16:3e:a0:cc:3f
        src_mac:  24:8a:07:8e:d3:15

  platform:
      master_thread_id: 0
      latency_thread_id: 14
      dual_if:
        - socket: 0
          threads: 
[1,2,3,4,5,6,7,8,9,10,11,12,13,28,29,30,31,32,33,34,35,36,37,38,39,40,41]


Please check the comment in the config file related to the use of MAC addresses:
https://github.com/opnfv/nfvbench/blob/master/nfvbench/cfg.default.yaml#L159

You basically need to configure nfvbench in EXT + no arp and put the dest MAC 
in the 2 fields (as described in the comment example)

Let me know if that addresses your problem.

Thanks

  Alec

Thanks,

Peter

You will need to be familiar with libvirt to try to replicate what openstack 
does to setup the VM properly: setup 2 virtual interfaces and provide a 
cloud-init config file.
This VM has VPP L3 routing included and that can be enabled/configured using 
the cloud-init file.
How well it will perform will really depends on your virtio network emulation 
(for example if you use OVS, it will likely not go very fast and start dropping 
packets very early).
Anyway, I can only help you to some extent as this stretches beyond what 
NFVbench handles.

Regards,

   Alec

Hi Alec,

Thank you for information, I would like to add an L3 loop VM (this would be the 
DUT to benchmark VMs performance). But I use NFVBench in EXT mode( so without 
openstack)

Peter

Peter,

This is outdated information.
With the latest versions of NFVbench, the testpmd VM image is included in the 
docker container itself (that way we make sure NFVbench always uses the right 
version of the VM image).
May I ask why you want to access this VM image?  To use it you will need to 
pass the proper config file to configure the forwarding dest MAC addresses 
(this is taken care of by NFVbench through openstack). If use openstack you do 
not need to manually get the qcow2 image and upload because it is done by 
NFVbench when using the PVP and PVVP chain types.

If you still need the VM qcow2 file, you can simply copy it out from the 
container using “docker cp” command. For example:

# docker exec nfvbench ls -l /nfvbench

Dear All,

I wanted to download testpmdvm-latest.qcow2 as recommended here

but testpmd VMs link looks as an internal 
http://172.29.172.152/downloads/nfvbench/testpmdvm-latest.qcow2

is this IP/link correct could you please send me the correct link.
