> It would be nice to have support for virtio-scsi for KVM hypervisors.
> The reason for using virtio-scsi instead of virtio-blk would be increasing the number
of devices you can attach to a vm, have ability to use discard and reclaim unused blocks from
the backend storage like ceph rbd. There are also talks about having a greater performance
advantage as well.
