[Feature Request] Provide 32bit CirrOS images

[Igor D.C.]

I have just installed devstack under a 32bit Ubuntu 12.04 LTS host and noticed that the bundled CirrOS images were all 64 bit.
Please consider bundling 32 bit images as well, at least when the host is 32 bit (and removing the 64 bit ones).

This also affected myself on my test machine

Having a quick look at the code, it appears $CIRROS_ARCH is not being set appropriately for non 64-bit architectures. Perhaps some autodetection code is needed?

CIRROS_ARCH=${CIRROS_ARCH:-"x86_64"}

The major reason I see for why this hasn't gone forward is when we have a multi-node deployment, where architectures might be different and consequently the default images wouldn't fit some machines. Why not provide both 32bit and 64bit images independently of the underlying architecture? Both 32bit and 64bit IA machines would have at least 1 compatible CirrOS version.

[Igor D.C. (igordcard)]

After further investigation, it seems more adequate to abandon this since it is possible to request a custom image through local.conf:

DOWNLOAD_DEFAULT_IMAGES=False
IMAGE_URLS+="http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-i386-disk.img"

This way, no assumptions need to be made about what the community/industry usually wants, and we keep it simple, consistent and predictable. Besides, this is also documented at:
http://docs.openstack.org/developer/devstack/configuration.html#guest-images

So, recommended way to get a 32bit CirrOS image on DevStack: do something like my example above.
