          Components: KVM, Storage Controller
    Affects Versions: 4.6.0

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.
