The man page for "virt-install -l" notes that this should work if virt-install is run as root. Is it run as root? The man page also suggests that you should be able to mount the ISO to a local directory and then use that path as the argument to "-l". Have you tried that to verify that the structure of the ISO filesystem is as expected?
