From: ShaoHe Feng <shaohef(a)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.
