I've used qemu-arm with a Fedora 20 image to run olpc-os-builder to
make an XO-4 image without Sugar and Gnome, and have booted this
on XO-4.  Next task is to run olpc-os-builder on the XO-4 to achieve
self-hosting.

apt-get install qemu-system-arm libguestfs-tools

wget http://mirror.aarnet.edu.au/pub/fedora/linux/releases/20/Images/armhfp/Fedora-Minimal-armhfp-20-1-sda.raw.xz

sudo virt-copy-out -a Fedora-Minimal-armhfp-20-1-sda.raw /boot/vmlinuz-3.11.10-301.fc20.armv7hl .
sudo virt-copy-out -a Fedora-Minimal-armhfp-20-1-sda.raw /boot/initramfs-3.11.10-301.fc20.armv7hl.img .

sudo qemu-system-arm -machine vexpress-a9 -m 1024 -nographic -net nic -net user  -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p3 rootwait physmap.enabled=0"  -kernel vmlinuz-3.11.10-301.fc20.armv7hl  -initrd initramfs-3.11.10-301.fc20.armv7hl.img  -sd Fedora-Minimal-armhfp-20-1-sda.raw

Add an additional repository to the .ini file.

Yes.

Underlying problem is XO-1 firmware does not have fs-update support.

For signed builds, where the firmware contains the deployment key:
http://wiki.laptop.org/go/Release_notes/13.2.1/Installation/XO-1/SD

For unsigned builds, you may use fs-update on an XO-1.5, XO-1.75, or
XO-4, and then move the SD card.

Alternatively, this Open Firmware fragment:
http://dev.laptop.org/~quozl/z/1XCG63.txt can be added to the top of
the 41001SL0.zd.zsp file (generated by olpc-os-builder), and then
manually loaded from the ok prompt:

ok fl u:\41001SL0.zd.zsp

This will then read the 41001SL0.zd file and store it on an SD card.

Perhaps olpc-os-builder should add this fragment.
