Hi Cristian, I don't know what ovirt is doing but if the final file is a raw image, you can shrink it with qemu-img and transform it in a qcow2. What I think was on the head of who implemented this is that you export a VM to a NAS that has normally Teras of space, so it is more compatible to save it in raw format. My 2 cents :-)
