So, the discovery component is a class named "discovery" in a module named
"discovery" in a package named "discovery". So it's...
discovery.discovery.discovery. You've only got discovery.discovery. I can see
how it's a bit confusing. :)
So try the following instead:
self._discovery = self.resolve(discovery.discovery)
Or alternatively, do:
self._discovery = self.resolve("nox.netapps.discovery.discovery.discovery")
(In this case, you don't even need the import statement)
