Pick one itself, or just not use one somehow? If it picks one, then we may need to treat this like we treat other rendernode instances and autoallocate one if the user doesn't specify, otherwise we won't be able to add the path to the cgroup for example, or selinux label it if necessary. I'm not sure if that actually applies in this case, but it's worth considering.
Even if we'll chose one automatically, we should at least output it in live XML.

Per https://libvirt.org/governance.html#codeofconduct we need your intentional agreement with the Developer Certificate of Origin: https://developercertificate.org/ to be able to include your changes. I'd be okay from stripping it from the patches you did not actually change, but it should stay on those where you actually changed something. Also, we do not have that process documented, but the kernel practice (and what I've been doing) seems to be that the maintainer merging the patch also adds a sign-off to provide that chain of certificates. Thirdly, I see some patches committed to libvirt by Marc-André but no mention in AUTHORS.in history - maybe it's time to get his commit access restored and documented?

Yes. Jano
