But after the machine rebooted, "ovn-sbctl show" is showing the correct fqdn: centos82.domain.tld, and it is causing VM instantiate error (Refusing to bind port <UUID> due to no OVN chassis for host: centos82.localdomain).

It looks like ceph-ansible was executed by tripleo but that
ceph-ansible isn't installed. Either install ceph-ansible or ensure
your deployment command does not include:

  -e /usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible.yaml
