We had some conversations last week and I was coding the support to 
multiple disks together with this patch,
then you asked me to stop and do later. So, this patch considered only 1 
disk per template. In this case the 'first'
and 'last' selection work fine.

Because the "option" elements only have the text.

This if statement do the following:
Suppose you have 2 storage pools of DIR type (dir1 and dir2), and a 
storage pool of iSCSI type (iscsi-pool).
When you select 'iscsi-pool' it is going to set disk format as RAW, and 
disable it. When you select a dir pool,
'dir1' for instance, it is going to enable and set disk format selection 
as 'qcow2' which is the default format.
Now, suppose you have 'dir1' selected and selects format as "vmdk". Then 
you change the pool to 'dir2',
it is NOT going to change the disk format to 'qcow2', keeping the 
previous selected value.
In other words, it avoids change the format to qcow2 every time, it only 
changes the format when changing
  from a storage pool with fixed format type ('raw') to a storage pool 
that accepts multiple formats.
