[ovirt-users] "Enable Discard" for Ceph/Cinder Disks?

Hi, according to http://docs.ceph.com/docs/luminous/rbd/qemu-rbd/ the use of Discard/TRIM for Ceph RBD disks is possible. Openstack seems to have implemented it (https://www.sebastien-han.fr/blog/2015/02/02/openstack-and-ceph-rbd-discard/). In oVirt there is no option "Enable Discard" for Cinder Disks (when choosing IDE or VirtIO-SCSI driver), even when i set "report_discard_supported = true" in Cinder. Are there plans for supporting this in the future? Can i use it right now with custom properties (never tried this before)? thx matthias
