Comment 5 for bug 565659

You're right. the descriptive text is wrong. In fact, I was typing the bug report up very quickly.

I did not want to change the size of the base image. Basically I just wanted to checkpoint my machine. So in fact, I couldn't bother less about the size and I thought qemu-img made me. But now I've just realised that you don't need to provide a size argument which I thought was mandatory.

Although I think it is very a corner case to reduce the image size and qemu should raise a warning if anybody attempts to decrease the image size, this could probably be closed as NOTABUG or so.
