This isn't a duplicate of bug 1678493 because that bug is about showing
console output for a server and it times out. This bug is about
launching an instance and it blows up because it's trying to rpc cast to
the nova-network service, which is probably not running. nova-network
will only start in a cells v1 configuration since ocata, and you
shouldn't be using it.

** This bug is no longer a duplicate of bug 1678493
   oslo_messaging.exceptions.MessagingTimeout

** Changed in: nova
