Backup: (UPDATE)
While i made my own backup script for Ovirt, i found this ansible based one.
https://github.com/silverorange/ovirt_ansible_backup

Backup Ovirt Engine using ansible

Usage : ansible-playbook -i ovirt-engine.lab, playbook.yml -u root (-k)

## Playbook
---
- hosts: all
  vars:
    ovirt_backup_mode: 'backup'
    ovirt_backup_archive: '/tmp/engine-backup.gzip'
    ovirt_backup_log_file: '/tmp/engine-backup.log'
    ovirt_backup_scope: 'all'
    ansible_python_interpreter: /usr/bin/python3
  roles:
      - ovirt-engine-backup

## roles/ovirt-engine-backup/tasks/main.yml
---
- name: run engine-backup
  shell: 'engine-backup --mode={{ ovirt_backup_mode }} --file={{ ovirt_backup_archive }} --log={{ ovirt_backup_log_file }} --scope={{ ovirt_backup_scope }}'
  tags:
    - skip_ansible_lint
  register: ovirt_backup_status

- name: download engine backup file
  fetch:
    src: "{{ ovirt_backup_archive }}"
    dest: "{{ ovirt_backup_archive }}"
  when: ovirt_backup_status is succeeded

- name: download log file
  fetch:
    src: "{{ ovirt_log_file }}"
    dest: "{{ ovirt_log_file }}"

Running Ovirt and want a overview of glustermounts in VMs?

run makeinventory.sh (this creats an list of linux hosts which are UP in RHV/Ovirt)

A php select page to few them

<form method="post">
<select name="volume">
    <?PHP
    foreach (glob("*.svg") as $filename) {
        echo "<option value=" . $filename .">" . $filename . "</option>";
    }
    ?>
    </select>
 <input type="submit" value="Submit">
</form>
<?PHP
    if (isset($_POST['volume'])){
            $image=$_POST['volume'];

Somewhere i've got a snapshot age warn script.
