Hi all, after some preliminary discussion on the QEMU mailing list, I present a draft specification for a virtio-based SCSI host (controller, HBA, you name it). The virtio SCSI host is the basis of an alternative storage stack for KVM. This stack would overcome several limitations of the current solution, virtio-blk: 1) scalability limitations: virtio-blk-over-PCI puts a strong upper limit on

This patch implements the hotplug support for virtio-scsi. When there is a device attached/detached, the virtio-scsi driver will be signaled via event virtual queue and it will add/remove the scsi device in question automatically. v2: handle no_event event v3: add handle event dropped, and typo fix Signed-off-by: Sen Wang <senwang at linux.vnet.ibm.com> Signed-off-by: Cong Meng <mc at

This implements the VIRTIO_SCSI_F_FC_HOST feature by reading the config fields and presenting them as sysfs fc_host attributes. The config change handler is added here because primary_active will toggle during migration.

Hi Rusty, here is the specification for a virtio-based SCSI host (controller, HBA, you name it) so that you can apply it to the spec document and publish it. I changed the index from 7 to 8 to account for the rpmsg device, and added a feature bit to tell the guest in advance whether the host supports hotplug. Otherwise there is no change from v2.
