So you would want to map an ISO9660 filesystem. In this case you would do: sudo targetcli /backstores/user:fbo create name=test_name cfgstring=/home/test/path.iso size=10000 Then you would map this backstore device to a fabric lun. Afterwards, on the client VM you would see this as dev/sr0 when you boot up. -Bryant -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
