* Fix OpenNebula inventory crash when NIC does not have IP
Match IPv6 behaviour.
When a NIC does not have an IP:
File "ansible/inventory/manager.py", line 292, in parse_source
plugin.parse(self._inventory, self._loader, source, cache=cache)
File "ansible-cm/plugins/inventory/opennebula.py", line 263, in parse
self._populate()
File "ansible-cm/plugins/inventory/opennebula.py", line 226, in _populate
servers = self._retrieve_servers(filter_by_label)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "ansible-cm/plugins/inventory/opennebula.py", line 210, in _retrieve_servers
server['v4_first_ip'] = self._get_vm_ipv4(vm)
^^^^^^^^^^^^^^^^^^^^^
File "ansible-cm/plugins/inventory/opennebula.py", line 154, in _get_vm_ipv4
return net['IP']
* Update to call to match IPv6 and add changelog fragment
* Update changelog fragment.
