Hi,
Have a windows guest 2019 server.
Controller: Virtio scsi single
hard drives:
scsi discard=on
io thread on
SSD emulation on

Yet, windows disk optimization continues to say "needs optimization (31% space effenciency) after trimming.

Wondering what's up with that? And if there's anything I can do about it?
