Overview

A virtio storage interface for efficient I/O that overcomes virtio-blk limitations and supports advanced SCSI hardware.

Status

Future tasks

  • QEMU Object Model (QOM) support for virtio-scsi device
  • Pick up vhost-scsi work again:
    • Port QEMU hw/virtio-scsi.c vhost-scsi support onto latest code
    • Port LIO vhost-scsi code onto latest lio.git code
    • Ensure vhost-scsi I/O still works
    • Design libvirt integration for LIO

Features

  • /dev/sda inside guest
  • Multiple LUNs per PCI adapter, solves virtio-blk 1:1 scalability problem
  • SCSI passthrough
