Soft-RoCE on mininet topology

Hi Team,

On two mininet VMs (on virtual box), I am able to run RDMA client and server and can also send traffic using rping tool. (Using link :- HowTo Configure Soft-RoCE https://community.mellanox.com/s/article/howto-configure-soft-roce )

Issue -

I have created 1switch 1 host topology on either VMs and connected both switch using GRE tunnel. (Host 1 can ping Host2 and also Host2 can ping Host1).

Now, I would like to make Host1 as RDMA Server and Host2 as RDMA Client, but whenever trying to couple veth with rxe device getting the error “sh: echo: I/O error”.

Can you please suggest on Soft-RoCE working for mininet topology.

Thanks

Hi Suraj,

Thank you for posting your question on the Mellanox Community.

Based on your information provided (We also noticed your posting on https://mailman.stanford.edu/pipermail/mininet-discuss/2018-August/008031.html https://mailman.stanford.edu/pipermail/mininet-discuss/2018-August/008031.html ), currently we do hot have support for running Soft-RoCE on a Mininet topology. Currently we only provided a method of running from a nic-2-nic.

Also please note that Soft-RoCE is still in BETA

We would recommend to post this question on the Mininet Mailings-list as you already did. Maybe somebody from the mailings-list has a solution for this as they need to implement this into the Mininet Framework

Thanks and regards,
