Title:
  Nova Not Setting Instance to ERROR State When ImageTooLarge Exception
  is Thrown

Status in OpenStack Compute (Nova):
  New

Bug description:
  Greetings,

  I noticed when a user creates an instance via the CLI and specifies a
  flavor that is too small for the guest image, the ImageTooLarge
  exception is thrown as expected, but the status of the instance is not
  changed from "BUILD" to "ERROR".

  This occurs with nova version: 1:2013.1.2-0ubuntu1~cloud0

  Steps to reproduce:

  * Create an instance through nova cli using a flavor with a root disk
  size that is smaller than the virtual size of the image.

  nova-compute.log output of the relevant section:
