Public bug reported: Shutting down a libvirt-lxc based instance will leak the nbd device. This happens because _teardown_container will only be called when libvirt domain's are running. During a shutdown, the domain is not running at the time of the destroy. Thus, _teardown_container is never called and the nbd device is never disconnected.
Steps to reproduce: 1) Create devstack using local.conf: https://gist.github.com/ramielrowe/6ae233dc2c2cd479498a 2) Create an instance 3) Perform ps ax |grep nbd on devstack host. Observe connected nbd device 4) Shutdown instance 5) Perform ps ax |grep nbd on devstack host. Observe connected nbd device 6) Delete instance 7) Perform ps ax |grep nbd on devstack host. Observe connected nbd device Nova has now leaked the nbd device. ** Affects: nova Importance: Undecided Assignee: Andrew Melton (andrew-melton) Status: New ** Changed in: nova Assignee: (unassigned) => Andrew Melton (andrew-melton) -- You received this bug notification because you are a member of Yahoo!
