what happens here if storageDomain returned one row above as null? (when
getting it from db from getStorageDomainDAO())

(!validate(storageDomainValidator.isDomainExistAndActive())) {

this method checks among other checks if domain is active, which is not exactly
an image validation.
Please consider renaming the method.

The casting to DiskImage is done here twice .
Since this is a downcasting operation, it is an overhead in runtime.
- please do it only once.
