Virtio will never support discard requests. Please use virtio-scsi.
So, please rename bug to "Feature request: Refuse to operate if virtio +
discard is requested"

Ideally there should be a warning if a user gives discard=unmap and
isn't using the SCSI bus. Using the following options allows the guest
to detect the drive as a thinly provisioned drive.
-drive discard=unmap,detect-
zeroes=unmap,cache=none,file=vms/win10.hd.img.vmdk,format=vmdk,if=none,id=hd
-d
