Purpose: bootstrapping XO-4 to Fedora 20 using QEMU.
Outcome: a .zd file for installation.
Ingredients
- an XO-4, the target,
- a conventional 32-bit or 64-bit computer running Ubuntu 14.04, the host,
- a USB drive.
Recipe
- install needed tools on the host,
apt-get install qemu-system-arm libguestfs-tools
- download the armhfp Fedora 20 Minimal image, from https://fedoraproject.org/wiki/Architectures/ARM/F20/Installation#For_Versatile_Express_Emulation_with_QEMU
wget http://mirror.aarnet.edu.au/pub/fedora/linux/releases/20/Images/armhfp/Fedora-Minimal-armhfp-20-1-sda.raw.xz
- extract the kernel and initramfs from the image,
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 .
- boot the emulated system,
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
