I am trying to include a post creation cloud-init password and hostname change to an instance, but nothing gets injected to the instance.

Tailing the logs I see the following message in the compute server logs.

Ignoring error injecting data into image ([Errno 13] Permission denied: 'rbd:compute

My compute node nova.conf has the option to allow the injection of passwords

Configure nova.conf
libvirt_inject_password=true
libvirt_inject_key=true
libvirt_inject_partition=-1

I WONDER if the problem could be the metadata api pulling from a different source.
