Bug Description

When trying to launch instance, I get this error message : Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class 'oslo_messaging.exceptions.MessagingTimeout'> (HTTP 500) (Request-ID: req-700f5d8c-5d88-4458-a918-3c31d3819fe3)

I checked the log file and I found :

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.
