The file qcow2.py was originally contributed in 2012 by Kevin Wolf,
but was not given traditional boilerplate headers at the time.  The
missing license was just rectified (commit 16306a7b39) using the
project-default GPLv2+, but as Vladimir is not at Red Hat, he did not
add a Copyright line.  All earlier contributions have come from CC'd
authors, where all but Stefan used a Red Hat address at the time of
the contribution, and that copyright carries over to the split to
qcow2_format.py (d5262c7124).

The git history shows which lines were contributed by IBM and is more
detailed than a single copyright line at the top of the file. It's also
common to make smaller contributions, like the one I made here, without
adding a copyright line. In light of this I see no issue with adding a
Red Hat copyright line and there is no need to add one for IBM:
