Emulating the XO/Quick Start/Mac

Installing QEMU for MacOS-X

You should already have an XO build image.

The port of Qemu for MacOSX is called Q and can be found in kju-app.org. Download and install Q.app stable version 0.9.0a89. Other builds are here: kberg.ch/q/builds/

Setting up

Q.app

Click on the (+) button to create a new guest:

Create new Guest:              Name:  OLPC
                   Operating System:  Q Standard Guest
                -- click (Create PC) --

Proceed to configure its preferences:

 General Prefs | SMB Filessharing:  No file sharing
Hardware Prefs |              RAM:  256 MB
Hardware Prefs |       Sound card:  ENSONIQ AudioPCI ES 1370
Hardware Prefs |     Network card:  rtl8139 PCI network adapter
Hardware Prefs |        Hard disk:  Select your unzipped build image
Advanced Prefs |   QEMU Arguments:  -redir tcp:2222::22  (but I had to leave this blank to work --IanOsgood)
                -- click (Create PC) --

For all QEMU Arguments, see Emulating_the_XO/Quick_Start. At the time of writing, it e.g. mentions -net user -net nic,model=rtl8139 as well - are those not needed on a Mac?? Anyhow, they can change/evolve, so please check the Quick Start page for the latest recommended arguments!

Also no CD-ROM? And no RAM disk? --IanOsgood 11:24, 15 November 2007 (EST)

To obtain an appropriate DPI (you get 75 by default), follow the instructions to add a Monitor section to xorg.conf on Emulating_the_XO/Help_and_tips#Font_Size_correction. The settings for 200 DPI to match the XO are "DisplaySize 130 97.5". Settings for 170 DPI may work better in emulation: "DisplaySize 153 115".

Starting OLPC Environment

Double click on the newly created "OLPC" to launch a window for it.
