I was thinking, if it's possible to assign more than one resource class to an Ironic

an oddball config, you could tag it as multiple resource classes that it's "close
enough" to for a match. But I'm not sure whether it's possible for an Ironic node to
be tagged with more than one resource class.
On the placement side, having an ironic node with two resource classes such as
RC1 and RC2, would mean that the ResourceProvider (the ironic node) would have
two inventory records: one for RC1, and another for RC2. When a request for a
flavor specifying one of these classes is handled, only the one class’s
inventory would be consumed. Placement would think that the node still had one
of the other resource class available, and would include that if another
request for that class is received, which would then fail as the node is
already in use.
Okay, so it's not possible to have one Ironic node with one inventory
record be classified as two different resource classes. Never mind that
idea then.
Thanks for pointing that out.
