[Hongbin Lu] A possibility is to revive nova-docker and engineer it as a thin layer to Zun. Zun has implemented several important functionalities, such as container lifecycle management, container networking with neutron, bind-mounting cinder volumes, etc. If nova-docker is engineered as a proxy to Zun, the burden of maintenance would be significant reduced. I believe Zun team would be happy to help to get the virt driver working well with Nova.
