The nova-docker virt driver is out of tree for nova and as far as I know
no longer maintained, so please don't report issues against nova, report
them against the nova-docker project and then after triage if they are
nova issues add nova to the bug report.

** Also affects: nova-docker
   Importance: Undecided
