[libvirt-users] FYI: Notes on setting up KVM guests using iSCSI

[David Ehle]

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?
