Description of problem:

I tried running a new instance from image (create new volume)
if device size remains 1 we can launch the instance and create the volume.
but if I change the device size to 30 we fail creating the volume with attribute error

Version-Release number of selected component (if applicable):

openstack-cinder-2013.2-0.9.b3.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
1. install Havana release 
2. create an image 
3. try to launch an instance from image (new volume) and add a bigger size to the device size filed. 

Actual results:

we fail to create the volume with attribute error 

Expected results:

we should succeed to create the volume
