一个设备实例代表一个 SCSI host ,上面有多个 target 和 lun attach 在上面。 virtio SCSI 设备服务两种 requests: - 对 lun 的命令请求; - Task Management Functions(TMF)。 Device ID 分配给 virtio-scsi 的 device id 是 8。 通过 lspci 可以查看。 00:0a.0 SCSI storage controller: Red Hat, Inc....

1、 怎么实现vhost_dev的VhostOps的vhost_set_vring_kick和vhost_set_vring_call; vhost_net kernel方式的vhost_set_vring_kick和vhost_set_vring_call依赖于/dev/vhost_net的ioctl。 有两种实现方式: 1、guest是server,dpdk vhost user是client 2、 guest是client,dpdk vhost user是server VHOST_SET_VRING_CALL...

iSCSI Target对外提供iSCSI服务,用户可以将运行SPDK服务的主机当前标准的iSCSI存储设备来使用;vhost-scsi或vhost-blk对qemu提供后端存储服务,qemu可以基于SPDK提供的后端存储为虚拟机挂载virtio-scsi或virtio-blk磁盘;NVMF对外提供基于NVMe协议的存储服务端。注意,图中vhost-blk在spdk-18.04版本中已实现,后面我们主要基于此...
Could we enable the similar strategy in NVMe-oF subsystem (for vhost blk or nvme, we know vhost scsi may be different ), that we could have multiple CPUs to serve on vhost? Author zhuohaofan commented Feb 26, 2021 For the test case, vhost is using just 1 CPU core to process the ...
