I would like to give a LGTM, but it's only the logging lines which I don't
like yet.
They seem like personal debug lines, but a admin will never know what they
actually mean.
In addition, I would like to see discard/unmap enabled by default for
Virtio-SCSI disks:

This will also allow for QCOW2 and RBD trimming.

> 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.
