Documentation: <https://help.ubuntu.com/community/UEC/Images>

The image itself:
<http://uec-images.ubuntu.com/oneiric/current/oneiric-server-cloudimg-armel-disk1.img>

This is the plain QCOW2 image. The normal one includes OMAP3/4(?) kernel
but I'll use the vexpress-a9 Linaro hwpack
    instead.

    michaelh@crucis:~/linaro/tests/qemu/img$ qemu-img info oneiric-server-cloudimg-armel-disk1.img
    image: oneiric-server-cloudimg-armel-disk1.img
    file format: qcow2
    virtual size: 808M (847203840 bytes)
    disk size: 198M
    cluster_size: 65536

Running with:

    qemu-system-arm -M vexpress-a9 -m 1024 \
    -drive file=../../img/ubuntu.img,if=sd,cache=writeback \
    -serial stdio \
    -append 'root=/dev/mmcblk0p1 rw mem=1024M console=ttyAMA0,38400n8 rootwait' \
    -kernel ../../img/tip/uImage -initrd ../../img/tip/uInitrd

Sits there saying:

<tt>2012-01-09 03:12:12,509 - DataSourceEc2.py\[WARNING\]:
'http://169.254.169.254' failed: url error \[\[Errno 111\] Connection
refused\]</tt>

Try different boot args:

    root=/dev/mmcblk0p1 rw mem=1024M console=ttyAMA0,38400n8 rootwait \
    init=/usr/lib/cloud-init/uncloud-init ubuntu-pass=ubuntu ds=unloud-init

Running:

    qemu-system-arm -M vexpress-a9 -m 1024 \
    -drive file=../../img/ubuntu.img,if=sd,cache=writeback \
    -serial stdio \
    -append 'root=/dev/mmcblk0p1 rw mem=1024M console=ttyAMA0,38400n8 rootwait init=/usr/lib/cloud-init/uncloud-init ubuntu-pass=ubuntu ds=nocloud' \
    -kernel ../../img/tip/uImage -initrd ../../img/tip/uInitrd

Fails
    with:

    Failed to execute /usr/lib/cloud-init/nocloud-init.  Attempting defaults...

Should be `uncloud-init`.

`uncloud-init` assumes the console is on `ttyS0`. Patch to ttyAMA0.

Final fault is the `ds=`. Should be nocloud which causes cloud-init to
use `DataSourceNoCloud.py`.
