This worked for me:

---
- hosts: localhost
  connection: local
  vars_files:
    - ../vars.yml

  tasks:
  - name: Obtain SSO token
    ovirt_auth:
      url: "{{ url }}"
      username: "{{ username }}"
      password: "{{ password }}"
      insecure: "{{ insecure }}"

  - name: List vms
    ovirt_vms_facts:
      fetch_nested: true
      nested_attributes:
        - description
      auth: "{{ ovirt_auth }}"

  - name: set vms
    set_fact:
       vm: "{{ item.name }}: {{ item.snapshots |
map(attribute='description') | join(',') }}"
    with_items: "{{ ovirt_vms }}"
    loop_control:
      label: "{{ item.name }}"
    register: all_vms

  - name: make a list
    set_fact: vms="{{ all_vms.results | map(attribute='ansible_facts.vm') |
list }}"

  - name: Print vms
    debug:
      var: vms

Can you please open an issue on Ansible github[1], and describe what
exactly issue do you have?
Thanks!
