I check the status of ovirt-provider-ovn. It's inactive.
[root@ovirt-manager ~]# systemctl status ovirt-provider-ovn
● ovirt-provider-ovn.service - oVirt OVN provider
Loaded: loaded (/usr/lib/systemd/system/ovirt-provider-ovn.service; disabled; vendor
preset: disabled)
Active: inactive (dead)
Then I start ovirt-provider-ovn service.
[root@ovirt-manager ~]# systemctl start ovirt-provider-ovn
[root@ovirt-manager ~]# systemctl status ovirt-provider-ovn
