Title:
  horizon boot from image (create a new volume) fails with ceph backend

Status in OpenStack Dashboard (Horizon):
  Expired

Bug description:
  Hi,

  This is bugging me since Kilo. Whenever i try to launch an instance
  from horizon with boot from image (create a new volume), it imediatly
  enters error state with invalid block device mapping as an error in
  dashboard. I am using ceph rbd as backend for cinder and glance.

  When booting from cli the process works as expected with the instace
  booting from a newly created volume. From what i can tell it is a wait
  time problem. Nova tries to attach the volume before the image gets
  downloaded from glance and it tries to attach volume None as /dev/vda.

  The only errors i found where in nova-compute.log :

  Steps to reproduce: 
  1. Ceph is backend to cinder and glance
  2. From dashboard launch an instance with "boot from image (create a new volume)".
  3. Get the error saying invalid block device mapping!

  Sorry if this bug has already been posted but i couldn't find it
