[Users] VM MAC-Ranges and setting custom MACs via API

Hi, I got some questions regarding the MAC-Range in the engine and how to utilize the set custom mac feature via API: We want to set a custom MAC per VM via REST-API (JSON) The RSDL tells me, that this should be possible in general. However, I have two questions: Must the specified custom MAC be within the range defined in engine? I suppose not, as this range should just be a pool to take MACs from when engine itself acquires one for a vm. Also some users in IRC could use imported vms with custom macs, but using REST might yield different results? Does this work via JSON in ovirt-engine 3.3.2 ? I just learned that the JSON implementation is not feature complete until 3.4. so I wonder if I can use JSON instead of XML to achieve this. I can not wait for the 3.4. release anyway. We had so far no problem with using JSON beside a nasty Cloud-Init (documentation)bug (BZ 1045484) and we don't want to rewrite all our code to generate XML instead of JSON if we can avoid it. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
