Hi Sagi,

I am using VMware 7.x as initiator with RDMA.
The target system is running Ubuntu 20.04.3 LTS with kernel 5.11.22+.

The device that is exported is an LVM volume, however I also tested with a file backed loop device.
Connecting with SPDK seems to be the problem and as reported on the SPDK mailing-list it can be used to reproduce the issue when VMWare is not available.
./perf -q 64 -P 1 -s 4096 -w read -t 300 -c 0x1 -o 4096 -r 'trtype:RDMA adrfam:IPv4 traddr:169.254.85.8 trsvcid:4420'

This seems to produce a similar result:
nvme connect --transport=rdma --queue-size=1024 --nqn=testnqn_1 --traddr=169.254.85.8 --trsvcid=4420

I hope this helps,

I meant which rdma device are you using? that device is failing the
qp creation.
