The wrong version of the preallocation patch has been applied, so this is the remaining diff. We can't use truncate to grow the image file to the right size because we don't know if metadata has been written after the last data cluster. In this case truncate would shrink the file and destroy its metadata. Write a zero sector at the end of the virtual disk instead to ensure that the file is big enough.
