workaround

change
/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-provider-ovn-driver/tasks/configure.yml
to be same as on ovirt-engine 4.5.4. (on the manager)

.
.
  when:
    - cluster_switch == "ovs" or (ovn_central is defined and ovn_central | ipaddr)
.
.
  when:
    - ovn_central is defined
    - ovn_central | ipaddr 

you will then get the same error as reported in
#695

"The conditional check 'cluster_switch == \"ovs\" or (ovn_central is defined | ipaddr)' failed. The error was: The ipaddr filter requires python's netaddr be installed on the ansible controller\n\nThe error appears to be in '/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-provider-ovn-driver/tasks/configure.yml': line 3, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n- block:\n    - name: Install ovs\n      ^ here\n",

to fix this , find out which version of python ansible is using

[root@vmmg-1 ~]# ansible --version
ansible [core 2.16.3]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.12/site-packages/ansible
  ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.12.1 (main, Feb 21 2024, 14:18:26) [GCC 8.5.0 20210514 (Red Hat 8.5.0-21)] (/usr/bin/python3.12)
  jinja version = 3.1.2
  libyaml = True

in my case, pyton3.12, then install netaddr for it

dnf install python3.12-pip.noarch
python3.12 -m pip  install netaddr

after that, adding new host in non default cluster works fine.

suggested fix, would be to revert the ovn configure.yml to what it was before, and auto install the netaddr ?
or figure out why it is failing to add on non default cluster and fix.

Hello
In my case, I have no OVN on my engine, but the OVN stuff got installed on the hosts, failing as well with same issue.
I hardly found a workaround :
Setting ovn_state: "unconfigured" in engine /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-provider-ovn-driver/defaults/main.yml
