Re: [Users] export VM
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 :-)

Hi Alex,
I don't understand what you mean by raw.
I was saying that the same file could be copied as a sparse file instead.
