Most input options are self-describing. If you want to save a local copy of
the image you create, provide a filename using the *-o* option. To upload the
-image to *pithos+*, provide valid cloud API access info (by either using a
-token with *-t* and a URL with *-a* pair or a cloud name with *-c*) and a
-filename using *-u*. If you also want to register the image with *~okeanos*, in
-addition to *-u* provide a registration name using *-r*. All images are
+image to the storage service of a cloud, provide valid cloud API access info
+(by either using a token and a URL with *-t* and *-a* respectively, or a cloud
+name with *-c*) and a remote filename using *-u*. If you also want to register
+the image with the compute service of the cloud, in addition to *-u* provide a
+registration name using *-r*. All images are
registered as *private*. Only the user that registers the image can create
VM's out of it. If you want the image to be visible by other user too, use the
*--public* option.
(ex. "Slackware Linux 14.0 with KDE")
* Registration Type: Private or Public
-After confirming, the image will be extracted, uploaded to *pithos+* and
-registered with *~okeanos*. The user will also be given the choice to keep a
-local copy of it.
+After confirming, the image will be extracted, uploaded to the storage service

For most users the functionality this mode provides should be sufficient.
In the *Register* sub-menu the user can provide:
* Which cloud account to use
- * A *pithos+* filename for the uploaded *diskdump* image
- * A name for the image to use when registering it with *~cyclades*, as well as
- the registration type (*private* or *public*)
+ * A filename for the uploaded *diskdump* image
+ * A name for the image to use when registering it with the storage service of
+ the cloud, as well as the registration type (*private* or *public*)
By choosing the *Extract* menu entry, the user can dump the image to the local
file system. Finally, if the user selects *Reset*, the system will ignore
.. image:: /snapshots/wizard.png
-Then you will be asked to provide a name, a description, a registration type
-(*private* or *public*) and the authentication token corresponding to your
-*~okeanos* account. Finally, you'll be asked to confirm the provided data.

-Choosing *YES* will create and upload the image to your *~okeanos* account.

Limitations
===========
Supported operating systems
---------------------------
-*snf-image-creator* can only fully function on input media hosting *Linux*
-systems. The program will detect the needed metadata and you may use it to
-upload and register other *Unix* or *Windows* images, but you cannot use it to
-shrink them or perform system preparation operations.

Logical Volumes
---------------
Para-virtualized drivers
------------------------
-*~Okeanos* uses the *VirtIO* framework. The disk I/O controller and the
-Ethernet cards on the VM instances are para-virtualized and need special
-*VirtIO* drivers. Those drivers are included in the Linux Kernel mainline since
-version 2.6.25 and are shipped with all the popular Linux distributions. The
-problem is that if the driver for the para-virtualized disk I/O controller is
-built as module, it needs to be preloaded using an initial ramdisk, otherwise
-the VM won't be able to boot.

Many popular Linux distributions, like Ubuntu and Debian, will automatically
create a generic initial ramdisk file that contains many different modules,
kvm using the *if=virtio* option (see the kvm command in the
`Creating a new image`_ section).
+For Windows and FreeBSD systems, the needed drivers need to be manually
+downloaded and installed on the media before the image creation process takes
+place. For *FreeBSD* the virtio drivers can be found
+`here <http://people.freebsd.org/~kuriyama/virtio/>`_. For Windows the drivers
+are hosted by the
+`Fedora Project <http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/>`_.
