Thanks Scott!
I have removed cloud-init from my instance and enabled config-drive in the
nova.conf file.
Anything else I should take notice of?

Cloud-init uses the "datasource" of the EC2 Metadata service, that
Openstack provides a workalike for.
That metadata service has things like "instance-id" and "hostname" that
are useful. cloud-init uses instance-id for "run-once-per-instance"
functionality.
cloud-init also gets user-data from the datasource, and that is very
useful for initializing images with information provided at launch time by
the user.
If you enable config-drive in openstack, then cloud-init will find the
same data above from the config-drive, and wont bother looking for the ec2
metadata service.
