Title:
  Kernel boot output missing from VNC/Spice consoles with AMI images

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) grizzly series:
  Fix Released

Bug description:
  If you are connected to a VNC or Spice console during the boot process
  of a VM which uses an AMI image, you will see no output.  This is
  because Nova passes only console=ttyS0 to the kernel, which makes the
  console log work but disables virtual terminal output.  Instead, Nova
  should pass two arguments:

  console=ttyS0 console=tty0

  Doing so is supported and confirmed to work, per the kernel docs:
  http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-kernel.html
