Cloud-init and rhev

I can get cfme to provision linux vms with templates on rhev but I am unable to get it working with cloud-init. cloud-init part is dropped or ignored.

cfme Version / Build

Q-task_id([r10000000000005_miq_provision_10000000000005]) MIQ(ManageIQ::Providers::Redhat::InfraManager::Provision#log_clone_options) Prov Options: [:customization_template_id]1 = “oVirt cloud-init”

On the rhev side, I can’t find cloud-init in

How does cfme inject the cloud-init info into vm? Mount a virtual floppy or iso ?
Is there anything special I need to modify on my vm template ?
Anywhere else can I look for logs, error messages?
