The "Storage pool" on Template represents where the guest disk will be 
created.
So if I specify "default" pool and size 10GB my guest will have a 10GB 
disk created on the default pool (under /var/lib/libvirt/images, for 
example)

But it is not true for iSCSI and SCSI pools.
We call the iSCSI and SCSI pools as read-only because we can not create 
new files on it.
The volumes are pre-configured by the system. Because that while using 
those pools you also need to select the volume as are represented by 
<pool_name>/<vol_name> in the combo box.

When a iSCSI or SCSI pool/volume is selected on Template the user can 
not edit its size, as the volume already exists and has a size.
