Sorry I thought I had already installed ovirt-provider-ovn-driver package
on hosts, as documented above, but It was not so...
This package in fact
provides /usr/lib/python2.7/site-packages/vdsm/tool/ovn_config.py that is
probably dynamically loaded by vdsm-tool command at runtime if found...

Nevertheless the rpm changelog for the package could be corrected
