Can i run a FFL container in no privileged mode？

[xinxinh2020]

Hi:
As far as i am concerned, now that freeflow is a resolution of RDMA virtualization, the container is no need to have the privilege to access the RDMA device in the host. After i install OFED in the original ubuntu container and commit it as a image named ubuntu_ffl ,I wonder if the bold fonts in the following is unnecessary when i use the ubuntu_ffl to run a ffl container?

sudo docker run --name node1 --net weave -e "FFR_NAME=router1" -e "FFR_ID=10" -e "LD_LIBRARY_PATH=/usr/lib" -e --ipc=container:router1 -v /sys/class/:/sys/class/ -v /freeflow:/freeflow -v /dev/:/dev/ --privileged --device=/dev/infiniband/uverbs0 --device=/dev/infiniband/rdma_cm -it -d ubuntu_ffl /bin/bash

So, i try it with the following command：

docker run --name node1 --net weave -e "FFR_NAME=router1" -e "FFR_ID=12" -e "LD_LIBRARY_PATH=/usr/lib"  --ipc=container:router1  -v /public/hxx/freeflow:/freeflow - -it -d ubuntu_ffl /bin/bash

Howerver，when i run ib_send_bw in this ffl，there are some errors occured， just like:

Is it wrong to run a ffl container in no privileged mode？Hope for your carification.
