so whats happening, i believe, is we copy the base template to primary storage. we then create a linked clone (the smaller volume youre seeing), and use that for the guest vm. If you destroy that vm, the linked clone will go away. The base image will get cleaned up sooner or later, as long as there are no other vm's running that depend on it. The cleanup will eventually happen depending on how aggressively you setup your cleanup intervals.
