I got a iSCSI target to work on my redhat with a USB disk to test
iSCSI storage pool and found below:
1. When create a iSCSI storage pool, I selected a target in dropdown list.
2. Once the pool is created, I see a volume named 'unit:0:0:1'.
3. When edit template, in the 'storage pool' dropdown, 'unit:0:0:1' is
listed there.
So 'unit:0:0:1' which indeed is a *volume* but listed as a *pool* in
template? or something I am misunderstanding?
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.
