[dpdk-users] dpdk docker container over VPP..

[Shiv Dev <shivfsdev@gmail.com>]

Hi Team,

  I am trying to run dpdk apps inside docker containers. These containers
have vhost-user interfaces connected to VPP.

  The memory regions in the VPP associated with the vhost-user are 0, which
might occur if the VHOST_USER_SET_MEM_TABLE message has not
reached VPP.

  Any ideas on how to debug the issue from the dpdk end ? Is there any way
to figure out if the virtio protocol handshake has been initiated ?

Regards,
Shiv

DPDK container configuration
-----------------------------------------

  I have compiled the dpdk app, and launching the docker with the below
command.

 -   sudo docker run -it -v /tmp/sock1.sock:/var/run/usvhost1 -v
/tmp/sock2.sock:/var/run/usvhost2 -v /dev/hugepages/:/dev/hugepages
dpdk-app-l2fwd

 - Subsequently, I launch the dpdk app..
