From: ShaoHe Feng <shaohef@linux.vnet.ibm.com> When the pool of template is iscsi or scsi, the volume parameter can not be NULL. And as we discussion, we do not mix disks from 2 different types of storage pools, for instance: we do not create a template with 2 disks, where one comes from a SCSI pool and other is a .img in a DIR pool.
