Targetting this feature to 4.3.6, as it needs lots of improvements on the UI design too

Comment 2 SATHEESARAN 2019-06-25 11:19:44 UTC
As per the last QE & Dev sync-up, it was decided the change requires the change in UI component as well
and its dependent on the requirement of LVM cache for non-VDO use case

Comment 3 SATHEESARAN 2019-09-03 05:18:36 UTC
verified with cockpit-ovirt-dashboard-0.13.6

LV cache section from the cockpit-wizard, now has clearly ask 
for the destination thinpool to be cached and it creates LV cache accordingly.
