Can't add new host to ovirt engine, because the following error:

2019-06-12 12:23:09,726 p=4134 u=engine |  fatal: [10.35.1.17]: FAILED! => {}

MSG:

The conditional check 'cluster_switch == "ovs" or (ovn_central is defined and ovn_central | ipaddr and ovn_engine_cluster_version is version_compare('4.2', '>='))' failed. The error was: The ipaddr filter requires python's netaddr be installed on the ansible controller

The error appears to be in '/home/engine/apps/engine/share/ovirt-engine/playbooks/roles/ovirt-provider-ovn-driver/tasks/configure.yml': line 3, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- block:
  - name: Install ovs
    ^ here
