Is there a Fedora issue for it? If so, could you add a reference for
that in this comment?
There's no Fedora's bugzilla or even libvirt issue about this error. The
error was found during the investigation of a different libvirt problem
and them a solution was submitted to libvirt ML.
I can add the reference to this patch sent to libvirt ML.
