Emulating the XO
| modify |
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.
See the Developer's Manual for a discussion of the general merits of the various packages and the ways you might want to use emulation in the development process. Always keep in mind that emulation is Not Perfect.
See Comparison of Alternatives for a grid showing which environments have been tested and found to work on which host operating systems.
- Configuration and Usage
- Tutorial Written by IBM on how to get this working.
- Improving emulation
If you are running linux, there is an experimental package to simplify using qemu for emulation. Feedback encouraged.
Build recommendations
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 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. MitchellNCharity 22:42, 14 December 2007 (EST)
- Joyride builds 1452 - current (2007-12-22) are not available for emulation (#5616 - ext3 disk images are missing). 1451 works. MitchellNCharity 13:56, 22 December 2007 (EST)
I've had good luck with all of the ship2 builds under VMware Workstation 6. Ed Borasky (Znmeb), 15 December 2007.
