I re-checked the versions with
[root@node05 ~]# rpm -qa | grep engine
ovirt-ansible-engine-setup-1.1.9-1.el7.noarch
ovirt-engine-appliance-4.3-20190416.1.el7.x86_64
ovirt-hosted-engine-ha-2.3.1-1.el7.noarch
ovirt-hosted-engine-setup-2.3.7-1.el7.noarch
ovirt-ansible-hosted-engine-setup-1.0.17-1.el7.noarch
python-ovirt-engine-sdk4-4.3.1-2.el7.x86_64
so probably I was already on the latest versions. I did not do any updated. First I was
doing a "rpm info" to get the version.
