1) Become forced_host enabled - either by being admin or by adding the role to a mere mortal user/tenant, or by removing the is_admin:True from the Nova policy.json file
2) Armed with the hostname of a compute node, flip one or more of the characters to upper case when passing that in through the --availability-zone option of Nova boot. For example if the hostname is "foo" use "Foo"
3) You will see a "no valid host found" once the instance goes into ERROR state.
