Re: [libvirt-users] FYI: Notes on setting up KVM guests using iSCSI
Daniel,
OK so I think I get it now. While for other storage backends one pool can
hold multiple volumes, when using iSCIS there is alwasy a 1 to 1
relationship for pool to volume? Each pool contains exactly one volume?

For iSCSI
- Pool == A single target
- Volume == A LUN within a target
So, if your iSCSI server exports many iSCSI targets, you'd setup a separate
pool for each target you want to access from libvirt. This post covers iSCSI
pool setup at a low level:
