Hi- To reproduce Anna's issue with rxe and iova's, I set up rxe on a Fedora 29 system. When I tried to run rxe_cfg after installing rdma-core, there were two additional packages that needed to be installed: perl-Getopt-Long libibverbs-utils Before everything was both hunky and dory. I didn't have the same issue with my Fedora 27 system. -- Chuck Lever
