Created a container with the ubuntu 18.04 image and using the rdma-shared device plugin, inside the container when running ib_write_bw it reports bellow error, but with ubuntu 20.04/22.04 it works well. so what's the reason behind causing this issue ? appreciated for any information.
Did not detect devices
If device exists, check if driver is up
