Public bug reported:

When booting Instance the hw_video_head property isn't retrieved from
the image metadata :

This functionality of modifying the number of  heads for spice users should have been added  in Ice-House 
according to BP :
https://blueprints.launchpad.net/nova/+spec/libvirt-video-driver-selection


I've tested the other video properties (hw_video_model ,  hw_video_ram )   and they seems to work fine ,
the only problem is  with:  'hw_video_head' . 

Steps: 
-----------

- nova flavor-key m1.small set hw_video:ram_max_mb=128

- glance image-update rhel64 --property hw_video_model=qxl
- glance image-update rhel64 --property hw_video_ram=64
- glance image-update rhel64 --property hw_video_head=2


+----------------------------+--------------------------------------+
| Property                   | Value                                |
+----------------------------+--------------------------------------+
| Property 'hw_video_head'   | 2                                    |
| Property 'hw_video_model'  | qxl                                |
| Property 'hw_video_ram'    | 64                                   |


- boot instance from that image ^^

Look at :
---------------
/var/lib/nova/instances/<Instace ID>/libvirt.xml 

<video>
      <model type="qxl" vram="64"/>
    </video>
  </devices>
</domain>


Results: 
------------
- the hw_video_head property isn't retrieved from the image metadata
- there's no mention of it  in the libvirt.xml
