Emulating the XO
This page is an inprogress overhaul of OS images for emulation.

Quick Start
Mac Quick Start
Linux Quick Start
1. Obtain qemu.
On Fedora, as root:
yum install qemu
On Debian/Ubuntu, as root:
apt-get install qemu
2. Obtain an image.
Download olpc-redhat-stream-development-ext3.img.bz2 (md5). Then,
bzcat olpc-redhat-stream-development-ext3.img.bz2 > laptop.img
3. Run qemu on the image.
qemu -soundhw es1370 -serial `tty` -hda laptop.img
4 (optional) Make qemu run faster.
If you want to use kqemu to speed up the emulation (on x86 and related cpus) then
modprobe kqemu major=0
and add the -kernel-kqemu option. See Using QEMU for Troubleshooting for tips.
We have heard multiple people say that QEMU doesn't work with these images on the debian-derived distributions. The symptom is that the kernel hangs during boot. There's a problem with bochsbios version 2.2, version 2.3 works. As a quick fix, apm=off can be added to OLPC kernel arguments. (For more info, see the discussion.)
If you have network problems through Qemu and OLPC, try this.
FreeBSD Quick Start
| Install qemu from ports: | cd /usr/ports/emulators/qemu && make install clean |
| or as a package | pkg_add -r qemu |
| Once installed, load kqemu and aio kernel modules: | kldload kqemu kldload aio |
| and launch the image you want: | qemu -hda olpc-stream-development-7-20060609_1600-ext3.img |
