Good catch. Obsoletes: python-libvirt is generated by %python_provide,
but I forgot to add Obsoletes: libvirt-python.
Thanks, I'll fix this and other packages in the same situation.

Yeah, that was a conscious decision. In the draft I sent to fedora-devel
last week I asked if python3 subpackages should be renamed, but nobody
answered, so I assumed that people don't care that much either way.
My motivation for not touching this right now was to limit the number
of changes and potential for screwups.

Not the prettiest, but rpm just doesn't give us nice tools. The
alternative is to repeat the description text three times, which is
not only at least as ugly, but also harder to maintain.
