Hi all
I just installed the urdma successfully. But I can not create rdma_create_event_channel with the command ib_send_bw. can you fix this problem? Thank you.

Do you have any clue for this problem? @qiuxiang008

I found the root cause is that we have to install user space driver to /lib and copy urdma.driver to /etc/libibverbs.d/

This error means that there are no available RDMA drivers. As @garywangcn pointed out, make sure that the driver library and configuration file are both installed into the correct location. Also check that the urdmad user service is running as the same user that is running the RDMA application. You can run ibv_devinfo to see if libibverbs can detect it.

@qiuxiang008 Are you still experiencing this issue?
