Hi Sebastian,
It seems your application is defaulting to IOVA_PA mode. Can you please check:
- You have enough permissions to access physical addresses (i.e: running as root)?
- The issue is not reproducible with "--iova-mode va" in the EAL parameters
- There is no other dpdk application (including ovs) running in the system.
- Does it always fail in the same point? i.e: just after "error allocating rte services array"

Thanks.

Comment 2 Marcin Mirecki 2019-12-17 08:30:50 UTC

Let me add more information on the issue.
- we are running on an openshift environment with mellanox sriov nic's.
- dpdk is running inside a container, build from ubi8, with the dpdk (downstream) package installed on it.
- inside the container we are working on a VF from the sriov nic, passed to the container by means of the Sriov CNI
- we are using the mlx5_core driver for the nic.

We also tried this with a custom build upstream version of dpdk, and it works fine.

Comment 3 David Marchand 2020-01-07 12:32:58 UTC

It should be a fairly similar issue to bz1785933.
I put a scratch build of the 18.11 dpdk package in it, can you have a try?
Thanks.

Comment 4 David Marchand 2020-01-13 10:23:33 UTC

Sebastian, Marcin,

Can you confirm this is the same issue than bz1785933?
Thanks.

Comment 5 Sebastian Scheinkman 2020-01-13 12:20:39 UTC

Hi David,

Yes, this is the same issue.
I was able to run the container without the privileged=true using the scratch build
