Open Stack

You need to set the node's resource_class attribute to the custom 
resource class you will use for that chassis/hardware type.

Then you need to add a specific extra_specs key/value to a flavor to 
indicate that that flavor is requesting that specific hardware type:

openstack flavor set $flavorname --property resources:$RESOURCE_CLASS=1

for instance, let's say you set your node's resource class to 
CUSTOM_METALLICA, you would do this to the flavor you are using to grab 
one of those Ironic resources:

openstack flavor set $flavorname --property resources:CUSTOM_METALLICA=1

Then nova boot with that flavor and you should be good to go.
