| - | If you do not have dedicated iSCSI target hardware, you will need to install the iSCSI Enterprise Target Daemon (ietd). If you are lucky, then your distro will already have packaged this for you; try installing a package called //iscsitarget// or //iscsi-target//. If this fails, you can download the source for the latest version from [[http://sourceforge.net/project/showfiles.php?group_id=108475&package_id=117141]]. | + | The procedure for exporting a disk image file depends upon the operating system that you are running **on your iSCSI target** (which may or may not be the same as the operating system contained within the disk image file). Instructions are available for: |

The iSCSI naming schemes are somewhat pedantic, but it won't affect anything in practice; as long as the target name is unique then everything will work just fine.) | + | |
