Bug Description
Binary package hint: qemu
Qemu 0.10.0 occasionally corrupts qcow2 images. The problem should be solved in 0.10.2.
This is how I observed it the first time:
$ qemu-img convert -c -O qcow2 wxpsp3-
qemu-img: error while reading
$ qemu-img info wxpsp3-
image: wxpsp3-
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 5.5G
cluster_size: 4096
highest_alloc: 5891559424

It turns out that the image was really corrupted, in fact qemu cannot use it (it says unbootable disk).
It was qemu itself that corrupted it, but I fear this is another problem, and I can not reproduce nor diagnose it.
So I think this bug should be closed, unless someone wants to see the corrupted image.
