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 all,

I see that exporting a VM with ThinProvisioning will make an image with the full disk size, instead of the currently used size:
- VM has a 20GB disk
- installed OS is taking 1.3GB
- exported disk is taking 20GB

Is this mandatory? Couldn't the export make a file with the same size, also sparse? It seems it only does a copy of the folder and the normal linux cp can make a sparse copy.

thank you,
Cristian Falcas

Is it exporting a a raw image, right?

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.
