[dpdk-dev] Inputs needed - testing l2fwd

[Shankari Vaidyalingam]

I'm trying to run sample DPDK  applications by injecting packets from an
external traffic generator.
I'm not able to get the frames to reach the RX queue of the corresponding
port and make the PMD detect those packets and get the application process
them.

My configuration is:

 I'm using Oracle VirtualBox to have 2 virtual network adapters for use in
the sample application. I have configured both the network adapters in the
"Bridged Networking" mode.
When I open the VM I can see the interfaces - eth0 and eth1
I bound the 2 interfaces to igb_uio driver and then configured the hugepage
mapping.
When I try sending the frames from an external source I had set the dest
MAC to the MAC addr of the ports bound to DPDK.
But still I'm not able to see either the "Frames received" or "Frames
dropped" count getting incremented.

I tried googling and tried various options for networking mode as
(Bridged/Host Only...) but none of them seem to work fine.

I'm sure that I'm missing something.
Can you please help me in this regard.

VirtualBox has its own version of virtio which is not compatiable
with the current version of DPDK virtio driver.

Hi,

I'm still facing the issue where I'm not able to receive the frames in the
l2fwd app that I'm running on the VM.
I also tried googling and read similar posts in the discussion lists but
not able to get the frames in the l2fwd app.
I've created the VMs using Oracle VirtualBox.
If anyone has tried using VirtualBox please let me know how to resolve this.
I tried running in both the ways but it didnt work:

(1)  Configuration inside a VM:

Traffic gen ------>  eth0 -------> L2fwd app -----> eth1

(2)

Traffic gen ---->  eth0 ----> VM (eth0) -----> L2fwd app -----> VM (eth1)
