Hi, I'm having the exact same problem doing a fresh install of RHEL and setting up (command line: hosted-engine --deploy --4) the ovirt-engine. I assume it must have been some kind of update to the base OS - (in my case RHEL 8.6 (Ootpa), because i have done previous installations with this exact OS and centos-release-ovirt45 repos without having an issues. The failed task is: TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up] and, on the hosted-engine log: /var/log/ovirt-hosted-engine-setup/engine-logs-2022-10-11T18:43:29Z/log/ovirt-engine/host-deploy I see: "stdout" : "fatal: [xxxxx]: FAILED! => {\"msg\": \"The conditional check 'cluster_switch == \\\"ovs\\\" or (ovn_central is defined and ovn_central | 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 5, 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\"}",
