I tried it two times, started with a intact image with the size above and in both times the image was corrupted. Host: WIN2K Guest: Debian 4.0 Etch. qemu: 0.90 (build date 2007-02-19, the version that comes with http://www.davereyn.co.uk/qem/setupqemuk40.exe) I tested the image above with virtualbox (installed backup of the qemu disk with acronis trueimage and bart pe boot cd) , started with the above image, and the problems are gone, image is now filled with more than 9GB, no problem so far. I never experienced such a bad problem with qemu before, maybe it is a problem with qcow2 format ?
