Hi, thanks for interesting demo! I am wondering how does this compare to 
"Discover nodes, knowing IP range for their BMCs and the default IPMI 
credentials" blueprint [1].

I really like the power of introspection rules. TripleO UI can nicely 
benefit from this, letting user provide rules to apply on introspection.

Regarding the autodiscovery use case, is it possible to somehow power up 
the machines using API? What if user does not know the $IPMI_HOST?

Can we replace enabling autodiscovery option in undercloud with 
discovering nodes as defined in [1] which would return json resembling 
to instackenv.json file and register the nodes using this? Does it make 

Can Ironic-inspector send messages via zaqar to notify subscribers about 
starting the autodiscovery?
