This lacks the "VIR_" prefix. Also I don't really see a point in adding
this. Currently it's used to distinguish between an encrypted QCOW and
an unencrypted QCOW. With LUKS (as you note later in a comment) it's
implied that they are encrypted and thus we don't need a side band to
store the same data.
