Permanent payload availability requires determining where the payload is stored.
Makes sense to me to store it together with the VM disks on the storage domain, but that requires the small object store which will not be available in the coming version (payloads can be large and keeping them in the DB and passing over the net every time the VM is run doesn't make much sense).

Wrt availability, I don't see a reason to exclude attaching both a CD and a payload via another CD at the same time (i.e. multiple devices).
