Description Jason Callaway 2014-04-01 18:23:03 UTC 
Description of problem:

When creating a new image in the Horizon dashboard, no minimum size is automatically set.  Further, the dialog will permit an invalid minimum size, which results in a block device mapping error during instance creation.

Steps to Reproduce:
1. In Horizon in the Admin tab, create a new image from http://download.fedoraproject.org/pub/fedora/linux/releases/20/Images/x86_64/Fedora-x86_64-20-20131211.1-sda.qcow2
2. Set the minimum size to 1GB
3. Launch an instance from the new image

Actual results:

Creation of the instance will fail after the 'mapping block device' phase.

Expected results:

Ideally the create image dialog should automatically populate the minimum size field.

At a minimum, the image creation process should fail specifying the invalid minimum size.
