Your libvirt-python version needs to be at least as new as your libvirt version. New libvirt-python versions are expected to continue to work with old libvirt versions as well (though it may need to be built against the specific libvirt?). In this case it looks like CentOS Stream 9 libvirt is newer than what was in constraints.
Generally constraints should update quickly. Looking at master upper-constraints libvirt-python was updated to 8.3.0 on May 4 and according to pypi the package updated on May 2 which seems reasonable. The problem here appears to be that you want this to work on a stable branch (yoga) and stable branches do not update constraints.
My suggestion is that we use stable platforms for testing stable releases. The CentOS Stream releases seem to get updates that break stable software expectations far more than our other platforms. When working against master and trying to chase the latest and greatest this is probably a feature, but is problematic when you want rate of change to fall to near zero. I would consider not using Stream on stable branches if these problems persist.
