It's working with virto-scsi,

but you also need discard support in your guest filesystem,

and also for your storage

(should work with ceph, iscsi block storage, local raw/qcow2 on top of host with filesystem with discard).
It don't work with nfs, lvm(local or on top of iscsi).

For me discard doesn't work with virtio disks. I did with scsi and 
virtio controller. Alexandre how it works for you?
