Hello, i had also a reproducible disk crash:
info of the last good image, size is about 3,5GB
image: debian4_0.dsk file format: qcow2 virtual size: 16G (16777216000 bytes)
disk size: 3.3G cluster_size: 4096
as soon as the image increase to a size of about 7,9 GB the emulator locks up,
and after a restart the the image is not readable any more.
the start of the image is filled with zeros, the signature of the file at the
start (QFI ....) is overwritten.
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 ?
Bye
HR
