Binary package hint: qemu
I try to recompress a qcow2 image that apparently is perfectly working, but qemu'img writes out about 60kB and, after about ten seconds spits an error. This is the first time this happens, few days ago I had used regularly this same command to compress old versions of this image.
This is qemu 0.10.0 from Jaunty. If necessary, I could provide the image.
$ qemu-img convert -c -O qcow2 wxpsp3-wlm-noacpi.qcow wxpsp3-wlm-noacpi.copia.qcow
qemu-img: error while reading
$ qemu-img info wxpsp3-wlm-noacpi.qcow

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-wlm-noacpi.qcow wxpsp3-wlm-noacpi.copia.qcow
qemu-img: error while reading
$ qemu-img info wxpsp3-wlm-noacpi.qcow
image: wxpsp3-wlm-noacpi.qcow
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 5.5G
