Thanks in advance! > It is not because of Perl :-) . In version 4 of the API it is mandatory to specify the NIC profile, as the network may have multiple profiles. So you need to find the identifier of that NIC profile and then send a request like this: <nic> <name>server.pic.es_nic1</name> <interface>virtio</interface> <vnic_profile id="the_id_of_the_profile"/> </nic> You can find the identifiers of the profiles like this: GET /ovirt-engine/api/networks/the_identifier_of_the_network/ vnicprofildes If you want the old behavior, the behavior of version 3 of the API, you can just add to your request the 'Version: 3' HTTP header. But note that version 3 of the API is deprecated since version 4.0 of the engine, and it will be removed with version 4.2 of the engine.
