[ubuntu] create non sparse qcow2 disk image

view full story

http://ubuntuforums.org – I have come to figure out that qemu-img will only create sparse qcow2 images. I even tried creating a raw file then converting but as soon as I convert it also converts to a sparse file. I don't get why during the original install using virt-install doesn't do this. I am trying to add a disk image to a windows 2008 server guest. It does not see the image at its full size but at its original which is basically nothing. Is there a way to create a non sparse qcow2 file? Thanks! (Hardware)
