It seems suboptimal for me: I would expect to see this kind of information in disks sub pane of the vm. Instead I have to select snaphsots sub pane, then for example the "Current' line, and at the right side sub pane in disks tab I see "Allocation Policy" - thin provision - make a clone of it in a new VM In the same sub pane for the new VM I see preallocated.... so it seems to work as I read This is on FC-SAN. What kind of storage is yours?
