@Thomas,
Is there really no way to detect the format other than relying on
extension? :-(

@smoser : fixed-size VHD images don't have a header, and there is AFAIK
currently no way for probing a footer in the QEMU code, so relying on
the extension seems to be the only way right now, as far as I can tell.
