+Notice the manifest rspec is essentially your request respec annotated with information about the resources that got allocated to you.  For example, the {{{<node>}}} element of the manifest includes the MAC and IP addresses assigned to each network interface on the node (host) and information you will need to ssh into the nodes (e.g. the fully qualified domain name of the host ).
