Title:
  libvirt: AMI-based Linux instances /dev/console unusable

Status in OpenStack Compute (Nova):
  In Progress
Status in Tempest:
  In Progress

Bug description:
  In Linux, the last console= option listed in /proc/cmdline becomes
  /dev/console, which is used for things like rescue mode, single-user
  mode, etc.  In the case of AMI-based Linux images, libvirt defines the
  "serial" console (tied to the console.log) last, which means a crashed
  instance ends up being unrecoverable

  Steps to Reproduce:

  1.  Upload the AMI/AKI/ARI images attached to this bug into Glance and tie them together (if how to do this is not common knowledge, I can follow-on with exact steps)
  2.  Boot an instance against the image.  It has been altered so that it will crash on startup, believing there is filesystem corruption

  Expected Behaviour:

  A "Press enter for maintenance (or type Control-D to continue):"
  prompt on the interactive console (Spice/VNC/etc.)

  Actual Behaviour:

  The aforementioned prompt appears in the libvirt console.log, and the
  instance is effectively bricked.
