Title:
  LXC termination fails using LVM for root

Status in OpenStack Compute (Nova):
  Triaged

Bug description:
  Hello,

  Terminating an instance running on LXC with LVM as instance root
  storage fails with an exception.

  The LVM volume is wiped using dd, but it is not disconnected from
  qemu-nbd before the LVM volume gets removed.

  The instance in itself on the compute node is stopped but still marked as Active, Deleting in nova. qemu-nbd is sill running.
  After first failure, disconnecting the qemu-nbd process manually and relaunching the instance termination works

  Log file in debug attached

  Environment:
  Ubuntu 12.04
  OpenStack grizzly

  Configuration for LVM:
  libvirt_images_type=lvm
  libvirt_images_volume_group=nova_local
