In the past, OLPC and the community produced [[wikipedia:Live CD|Live CDs]], allowing OLPC's "Sugar" interface to be run on "regular computers" without making any permanent changes to the system. Today, Sugar is developed as a generic project and is available in various different live media forms, see '''[http://wiki.sugarlabs.org/go/Downloads Sugar Labs Downloads]'''.
A '''[[wikipedia:Live CD|Live CD]]''' is a bootable medium which has an operating system that can run upon boot; you don't need to install it to internal storage. It lets a user to try out a new operating system without making any permanent changes. Live CDs are generally distributed as <tt>.iso</tt> (ISO 9660) images. You download the <tt>.iso</tt> image and then burn it to a CD-ROM using a program that can create a CD from a file (note that MS Windows XP cannot do this natively, please do not copy an ISO image .iso file to CD; it's not what you want), or copy it to a prepared USB key, or install it on a virtual machine.

Several efforts are underway to create a live CD emulating the XO and the Sugar environment.

== Various efforts ==
In general, Live CDs either take an OLPC build (based on [[Fedora]]) and create a Live CD, or take a [[:Category:Linux distributions|Linux distribution]]'s Live CD machinery and add Sugar packages.

These Live CDs allow you to convert a "regular" machine into a Sugar-running machine without touching the hard disk of the machine. This allows you to play with and test how the software runs with your hardware. It also lets you demonstrate and potentially test your software (at full speed).

It is also possible to use this type of Live CD to create a "virtual Sugar lab" for a school, where a traditional computer lab's computers are booted into a Sugar environment, storing their data on a networked or other storage device, without changing the lab's installed software. (How? Link would be appreciated)

A [http://startx.ro/sugar/ XUbuntu Live CD] with the Sugar Ubuntu package (with installation capability and launch-from-USB-key). Allows you to run Sugar directly on the hardware with an XUbuntu environment as well. A full working Live-CD with a recent build is available.

http://ubuntuforums.org/showthread.php?t=670171 has further discussion.

=== Fedora Sugar Spin ===

'''Notes:''' Sebastian Dziallas reports that there is a Sugar spin based on Fedora available here:

http://alt.fedoraproject.org/pub/alt/olpc/0.82/i686/sugar-spin.iso

Please ''be aware'' of the fact that the link above has changed recently - the old one won't work anymore! For more information, please see this post: https://www.redhat.com/archives/fedora-olpc-list/2008-November/msg00003.html

With this spin, you'll be able to run Sugar, which is developed by Sugarlabs and the desktop environment used on the OLPC, directly from a Live CD! You'll find several activities on the image including most notably...

* sugar-browse - a web browsing activity based on xulrunner
* sugar-write - a word processor based on abiword

...among with several other applications introducing e.g. chat support.

The OLPC SIG, will be importing further activities into Fedora, which might be installed using ''yum install sugar-*'' at a later time.

The SHA1 checksum is, if you're interested:

''f032ab45aa116c2728dcd2d676e29a5ee114fd1d'' sugar-spin.iso

What if you wanted to put it quickly onto your USB Key? You'll just need to grab Luke Macken's liveusb-creator, which already includes support for the Sugar Spin. Here's the link:

https://fedorahosted.org/releases/l/i/liveusb-creator/liveusb-creator-3.0.zip

The liveusb-creator still contains the old link, which is the reason why you'll need to download the spin manually until this gets fixed.

'''Thank you everybody, who made this possible!'''


=== Pilgrim Fedora Live CD ===

A [http://gregdek.livejournal.com/19843.html Fedora Pilgrim Live CD] with the official image pre-downloaded and configured to run in Qemu with KQemu. Allows you to run the image from the standard Fedora desktop inside an emulator.

== OLPC XO-1 Live CD (obsolete) ==
''Note:

''This Live CD has not been updated since early April 2007. Much which now works, was not even started back then.
''The maintainers seem to have abandoned it. Greg DeKoenigsberg took a look at another way to automatically generate Live CDs in a [http://gregdek.livejournal.com/19843.html recent blog post], but this is apparently still a work-in-progress.

''Until someone starts maintaining this again, it looks like the best way is to go with [[#Various efforts|other Live CDs listed above]], or work with the XO software is via [[emulation]]''

The Live CD may not boot off an external optical-drive connected via USB.
