[sheepdog-users] reclaim space with virtio-scsi discard

Just tried to use "discard" feature of virtio-scsi and noticed that 
before my test vdi had 1,3Gb allocated due to "dog vdi list" output and 
after downloading-deleting some iso files inside VM there are 2,8Gb 
allocated. FS is ext4, mounted with flag "discard". Tried to do fstrim 
with the same result.

Is it means that discard isn't supported by sheepdog?
