Hello, I just tried this on a eoan vm, but didn't experience the same as you. I did: rxe_cfg start rxe_cfg add ens2 (my nic)
Now I have: root@eoan:~# rxe_cfg status Name Link Driver Speed NMTU IPv4_addr RDEV RMTU ens2 yes virtio_net 1458 10.48.132.219 rxe0 1024 (3) root@eoan:~# rxe_cfg persistent ens2 Could you please verify your steps and try to reproduce this on a clean eoan vm? And maybe attach logs, like dmesg and /var/log/syslog. For example, my dmesg recorded this: [ 59.829728] rdma_rxe: loaded [ 88.526483] infiniband rxe0: set active [ 88.526487] infiniband rxe0: added ens2 [ 88.659926] Loading iSCSI transport class v2.0-870.
