File backend/manager/dbscripts/create_views.sql
Line 69: LEFT OUTER JOIN base_disks ON images.image_group_id = 
base_disks.disk_id
agreed count(device_id) and count(*) will have the same result.

using count(*) will allow the database some optiomizations that 
count(device_id) doesn't.

Line 232:     LEFT JOIN
disagree, but it's a matter of taste.

Line 14: 
You just added the number_of_vms fields in this patch, no?

we obviously have a missunderstanding.

Line 81:             VmEntityType vmEntityType,
same answer :-)

Line 21:     private VmEntityType vmEntityType;
I think you should change it.

In the database, there is no way this can be null (you use coalesce to ensure 
that) - the BE should reflect that.
