[Qemu-devel] [Bug 784977] [NEW] qemu-img convert fails to convert, generates a 512byte file output

[Andy Brook]

Public bug reported:

I have a Vmware image, so I have files like 'Ubuntu.vmdk', want to
convert to VirtualBox .vdi format using qemu, the first stage of
extracting the image with 'qemu-img convert Ubuntu.vmdk output.bin' just
generates a 512byte file:
