Hope it can help you to get start with it.
Unfortunatly I have already gone through these documents, several times as
well, but these are only about the creation of storage pools, not how you
attach them to the guest.
If the pool is ready, here are kinds of examples
http://libvirt.org/formatdomain.html#elementsDisks
you can use it in guest like this:
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='iscsi-pool' volume='unit:0:0:1'
mode='host'/>
<auth username='myuser'>
<secret type='iscsi' usage='libvirtiscsi'/>
</auth>
<target dev='vdb' bus='virtio'/>
</disk>
Do I attach a storage pool as a disk. Like: -drive pool="pool-name", and if
so, how do I do with index numbering, since the pool can hold several LUN's?
Perhaps the code takes care of the indexing, since the LU's got numbers...?
Or do I have to attach every LU in the pool individually? With their own
index number?
