oVirt-Engine: Changing FQDN and updating the certs

Example from engine machine:

#engine-machine> /usr/share/ovirt-engine/setup/bin/ovirt-engine-rename \

     --newname=newnameEngine.ocp.medogz.home \

     --otopi-environment="OSETUP_RENAME/forceIgnoreAIAInCA=bool:'True' \

     OVESETUP_CORE/engineStop=bool:'True' \

     OSETUP_RENAME/confirmForceOverwrite=bool:'False'"

# systemctl restart ovirt-engine

# systemctl restart ovirt-imageio-proxy

Worked like a charm, more info: https://www.ovirt.org/develop/networking/changing-engine-hostname.html
