[one-users] OCCI 3 Requests

[florian.feldhaus at tu-dortmund.de]

Hi Amine,

The GET commands you are issuing are returning a HTTP return code 200 OK. It will return nothing, if you didn't successfully create a network, storage or compute object before. Regarding the POST: If you are using OCCI v0.3, then you should use the attribute as described here:
http://dev.opennebula.org/projects/ogf-occi/wiki/Occi_03

The virtualnetwork mixin was necessary for OpenNebula 2.2 but we decided to not support OpenNebula 2.2 anymore as it is missing some important features (like VLAN) for successfully mapping OCCI attributes. Thus, please use OpenNebula 3.0 together with OCCI v0.3 and then creating networks shouldn't be a problem.

Cheers,
Florian
