Hi, I was trying to run qemu with spdk, referring to http://www.spdk.io/doc/ vhost.html#vhost_qemu_config . Steps were strictly followed.
# Environment: latest CentOS 7 kernel, nvme ssd, spdk v18.01.x, > dpdk 17.11.1, qemu 2.11.1 cd spdk > sudo su > ulimit -l unlimited > HUGEMEM=2048 ./scripts/setup.sh > ./app/vhost/vhost -S /var/tmp -s 1024 -m 0x1 & > ./scripts/rpc.py construct_nvme_bdev -b Nvme0 -t pcie -a 0000:03:00.0 > ./scripts/rpc.py construct_malloc_bdev 128 4096 -b Malloc0 > ./scripts/rpc.py construct_vhost_scsi_controller --cpumask 0x1 vhost.0 > ./scripts/rpc.py add_vhost_scsi_lun vhost.0 0 Nvme0n1 > ./scripts/rpc.py add_vhost_scsi_lun vhost.0 1 Malloc0 > > qemu-system-x86_64 -enable-kvm -cpu host -machine pc,accel=kvm -daemonize > -vnc :1 \ > -smp 1 -m 1G -object > memory-backend-file,id=mem0,size=1G,mem-path=/dev/hugepages,share=on -numa > node,memdev=mem0 \ > -drive file=<guest-os-image.qcow2>,if=none,id=disk -device > ide-hd,drive=disk,bootindex=0 \ > -chardev socket,id=spdk_vhost_scsi0,path=/var/tmp/vhost.0 \ > -device vhost-user-scsi-pci,id=scsi0,chardev=spdk_vhost_scsi0 Unfortunately the demo was not able to work, stopped at the boot-loader screen saying that not bootable device. But if I removed the last two lines( vhost-user-scsi-pci), the guest could start successfully. So there must be something wrong with the spdk device. Is there anyone in this community who happened to be familiar with spdk? Or should I seek for help from Intel? Don't know who is responsible for maintaining this document. Thanks, Bob
