I wouldn't use the node metadata as a "transport" for the properties between methods. Instead, I would:
* Create a new type to transport the information, say NodeAndOptions or NodeAndTemplate, that has a reference to the NodeMetadata and to the TemplateOptions (or Template). * Modify the deflaration of the AllocateAndAddFloatingIpToNode class to accept that type as an input. * Modify the ApplyNovaTemplateOptionsCreateNodesWithGroupEncodedIntoNameThenAddToSet here [1]. That line transforms each node with the function to allocate and add the IPs. You could chain the transformations: first convert them to NodeAndOptions and then apply the allocation IP function. WDYT? I.
