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]]. |

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) |

: Another jabber server alternative is: jabber.xochat.org (typically 60 to 80 people online) --[[User:IainDavidson|IainD]] 03:29, 5 January 2008 (EST) |

: Please be aware that the xochat.org server is also overloaded, and the load is proportional to the product of the number of registrees times the current number of users, for the reasons documented at [[XMPP_Extensions]]. So don't connect (and thus automatically register) unless you will really be contributing, and/or set up your own ejabberd server. [[User:NealMcBurnett|NealMcBurnett]] 15:39, 7 January 2008 (EST) |

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.
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!
