<p class="MsoNormal">Here is a spec about Mogan and Valence integration[1], but before this happen, I would like to know what information needed when requesting to compose a node through Valence. From the API doc[2], I can only find name and description parameters,
but seems like it's incorrect, I suppose that it should at least include cpus, ram, disk or maybe cpuinfo. We need to align with this before introducing a new flavor for both RSD nodes and generic nodes.<o:p></o:p></p>
