Description

  • Let's discuss the state of zoned storage in QEMU and any questions
    about using zoned storage in QEMU.
  • Zoned block devices on Linux can now be exposed to VMs via SCSI ZBC
    and virtio-blk emulation.
  • SCSI devices can also be passed through (scsi-generic) and physical
    PCI adapters can be assigned to VMs if you don't want QEMU emulation
    involved.
  • There is work in progress to support NVMe ZNS, which currently only
    offers volatile zone state and is not suitable for running production
    VMs yet.
  • There is also work in progress to support emulating zones inside
    qcow2 files for testing and bring-up.
