From the perspective of a CIM provider, being able to correlate the
storage used by any set of domains (be them virtual machines or a
containers) to each other is important.
Even if you can't provision* an overlay directory with libvirt (in the
way that this API lets you provision an LV), being able to model the
existence of one is important.
I don't think this will change the XML of a container, but it will
give us a way to associate the path provided for a mount to a storage
pool.
[*] provisioning in the containers case would be a recursive directory
copy of a template overlay directory, which is what Dan was saying
he didn't want to do
