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 '''[http://en.wikipedia.org/wiki/LiveCD LiveCD]''' is a bootable medium which has an operating system executed upon boot without installing to internal storage. It provides a method for a user to try out a new operating system without making any permanent changes. LiveCDs are generally distributed as .iso (ISO 9660) images. The .iso images are downloaded and then burned onto 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), copied to a prepared USB key, or installed on a virtual machine.


Information regarding old LiveCD projects based around very old OLPC software releases can be found at [[LiveCd/Historical]].
Several efforts are underway to create a liveCD emulating the XO and the Sugar environment.

These LiveCDs 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 LiveCD 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)

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://sdz.fedorapeople.org/olpc/sugar-spin.iso

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:

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

=== Pilgrim Fedora LiveCD ===

A [http://gregdek.livejournal.com/19843.html Fedora Pilgrim LiveCD] 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.

''The LiveCD 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 LiveCDs 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 [[LiveCd#Current_efforts|other LiveCDs listed above]], or work with the XO software is via [[emulation]]''

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