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. |

Note, XOs are readily available to genuine volunteer contributors through the [[Contributors program]]. |

For many, the [[LiveCd|LiveCD]] is the easiest way to try [[Sugar]]. It's easy to do, but your work is lost when you reboot. |

'''[[Emulating the XO/Quick Start|Emulation]]''' is the other way to try [[Sugar]]. It can be harder to set up,, but work is preserved. |

== Quick Start for Developers == |
|||
Developing on emulation is one alternative for developing software. |
|||
Get [http://olpc.download.redhat.com/olpc/streams/development/LATEST/devel_ext3/olpc-redhat-stream-development-devel_ext3.img.bz2 the latest image] |
|||
from [http://olpc.download.redhat.com/olpc/streams/development/LATEST/devel_ext3/ here]. ''(add link to tinderbox)'' |
|||
Install QEMU and kernel acceleration as described in [[Emulating the XO/Quick Start]]. See [[/Help_and_tips#Development]]. |
|||
Build 451 has been reported to not boot under qemu. 445 is known to work. |
|||
== Overview == |
|||
One way to run oplc software is using an emulator on your pc. See [[Getting started programming]] for other options. |
|||
Note '''[[:Category:Emulation]]''' and '''[[Emulating the XO/Help and tips|Help and tips]]'''. |
|||
For play, you can use [[LiveCd]] or [[Emulating the XO/Quick Start|Quick Start]]. |
|||
For development, you can use [[LiveCd]], or qemu (as in quick start, but with a different image), or perhaps one of the [[Developer Images]] other than the LiveCd. An alternate approach is to attempt [[:Category:Installing_Sugar|installing sugar]]. See [[Getting started programming]] for a comparison. |
|||
A common development approach is to use [[QEMU]] with kqemu acceleration. See [[Emulating the XO/Quick Start|Quick Start]] for the basics. |
|||
Though for development, we will use a different .img, one with a few extra utility programs. See [[OS images]], including '''[[OS_images#Latest_Stable_Build |latest stable build]]'''. |
|||
Instead of qemu, you can run [[Emulating the XO/UsingVMware|VMware]], and there are additional options on a [[Emulating the XO/Mac|Mac]]. |
|||
Please report your experiences in [[User Feedback on Images]]. There is a [[Virtualization Common Room]]. |
|||
There are [[Emulating the XO/Limitations of XO disk images|limitations with XO disk images]]. |
|||
The LATEST-STABLE-BUILD versus LATEST build distinction is mostly of interest to people running on actual XO's. In emulation, developers should usually use LATEST. And when STABLE is old, non-developers probably should too. |
|||
== Comparison of alternatives == |
|||
An OLPC laptop is custom hardware, running a stripped-down Red Hat linux, running [[Sugar]]. But what if you don't have a real olpc laptop? There are a several options. |

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!
