| + | 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. However, these images had limitations and were a drain on resources to produce and maintain. |

| - | | + | |
| - | 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.

| - | == Quick Start for Developers ==
| + | |
| - | Developing on emulation is one alternative for developing software.

| + | |
| - | Install QEMU and kernel acceleration as described in [[Emulating the XO/Quick Start]]. See [[/Help_and_tips#Development]].
| + | |
| - | | + | |
| - | Builds 463,461,451 do 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, which can each be used in a couple of ways.

| | + | [http://sugarlabs.org Sugar], the unique user interface of the XO laptops, is now distributed as a generic software project and can be easily installed, developed and tested on "regular" computers as well as XOs. See [http://wiki.sugarlabs.org/go/Downloads Sugar Labs Downloads] for the full range of options, such as [http://wiki.sugarlabs.org/go/Sugar_on_a_Stick Sugar on a Stick]. |
| | | | |
| | + | For emulation of very 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. |
