The RNG already has all the proper formats defined when it was added in commit id 'c00b2f0d' (if you use gitk you can see other similar commits around that time as well). That same commit updated formatdomain.html.in, but changes since then (commit id 'cb3b7dce7') adjusted the wording slightly to the current test to describe use of "<source type='volume'...", although perhaps still not quite precise with respect to indicating how "<disk... type="block|network" ... device='lun'" is described. I suppose I could add something like the following to the paragraph that starts "Use the attribute mode...": Using a LUN from an iSCSI source pool provides the same capabilities as a <code>disk</code> configured using <code>type</code> 'block' or 'network and <code>device</code> of 'lun' with respect to how the LUN is presented to and may used by the guest. Possible replacement for "capabilities" - "features"? Or some other suggestion. John -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
