I guess "extra virtualization layer" means Magnum provisions a Container
Orchestration Engines (COE) on top of nova instances. If the nova instances
are virtual machines, there is a "extra virtualization layer".

I think you could consider using Magnum with Ironic driver. If the driver
is Ironic, COEs are deployed to nova instances that are physical machines
provided by Ironic. Zun project [1] could be another option for your use
case. Zun is similar to nova-docker, which enables running containers on
compute hosts. You could find a thoughtful introduction here [2].
