Thanks for posting that article, I've left some comments and questions
in there for you. :)
Once I realized that conductor was timing out waiting for the response
from the scheduler select_destinations() call, bumping the
rpc_response_timeout config made things work.
Note that in my single-node fake driver devstack setup here I'm not
creating real guests nor am I setting up networking. For the purpose of
my test I was just interested in the conductor/scheduler/placement
service interaction, not so much with the actual guest creation that
happens in the compute service.
