In the past, OLPC produced alternative software images which could be run in emulators such as QEMU and VMware. This meant that development and testing could happen to a limited extent without requiring an XO laptop. |

Emulators allow you to run a "virtual machine" on a (reasonably powerful) host machine. There are a number of emulator systems available which can be used to run a simulated OLPC-XO. |

For running XO disk images on an emulator, some builds are better than others, and the most recent one will not always work. Here is a summary of current status. Please add your own experiences here, and in [[User Feedback on Images]]. |
|||
Current [http://xs-dev.laptop.org/~cscott/olpc/streams/joyride/ joyride] builds generally work (as of ~1400). |
|||
Presence service (mesh view and collaboration) wont work by default, because they are configured with a presence service providing jabber server of ship2.jabber.laptop.org, which doesn't yet exist. There is an overloaded and fragile jabber.laptop.org which may be used in the meantime. [[User:MitchellNCharity|MitchellNCharity]] 22:42, 14 December 2007 (EST) |

:Joyride builds 1452 - current (2007-12-22) are ''not'' working in emulation ([http://dev.laptop.org/ticket/5616 #5616] - ext3 disk images are missing). 1451 works. [[User:MitchellNCharity|MitchellNCharity]] 13:56, 22 December 2007 (EST) |

For emulation of extremely old builds, you may be able to come across "ext3 images" on some corners of http://download.laptop.org and http://xs-dev.laptop.org/~cscott/olpc/streams/ which can be loaded into emulators. You are unlikely to find support for them! |

In the past, OLPC produced alternative software images which could be run in emulators such as QEMU and VMware. This meant that development and testing could happen to a limited extent without requiring an XO laptop.
In 2013, please see Tom Gilliard's many virtual machine images ready-to-go.
Note, XOs are readily available to genuine volunteer contributors through the Contributors program.
Sugar, the unique user interface of the XO laptops, is also distributed as a generic software project and can be developed and tested on "regular" computers as well as XOs. See Sugar Labs Downloads for the full range of options, such as Sugar on a Stick.
