# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

# Create MAC pool:
- ovirt_mac_pool:
    name: mymacpool
    allow_duplicates: false
    ranges:
      - 00:1a:4a:16:01:51,00:1a:4a:16:01:61
      - 00:1a:4a:16:02:51,00:1a:4a:16:02:61

# Remove MAC pool:
- ovirt_mac_pool:
    state: absent
    name: mymacpool

# Change MAC pool Name
- ovirt_nic:
