When NVMf target linked with vfio-user library, we can use vfio-user client library to connect to the target. Here is the three examples that can work with target: identify -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g perf -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 1 -o 4096 -w read -t 10 reconnect -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 32 -o 4096 -w randrw \ -M 50 -t 10 -c 0xE You can run the following test script test/nvmf/target/nvmf_vfio_user.sh to have a quick test, currently enabled with NVMe Identify,Perf,Reconnect tools.
