** Description changed: == Begin SRU Information == [Impact] 'config-drive' is a mechanism for passing data from the hypervisor (or cloud platform) to the guest (instance). config-drive-v2 was implemented in Openstack Folsom release, and delivered as functional in 12.10 Ubuntu. In order to support Ubuntu 12.04 cloud images running as a guest on Openstack clouds that utilize config-drive, we need to backport this function to 12.04. This feature backport can be considered "hardware enablement" as it enables Ubuntu images to work on new cloud platforms. [Test Case] Attached to this bug is an ISO that provides config-drive-v2 data. Currently, if you attach the ISO to a cloud-image instance, it will be ignored. The new version of cloud-init enables data to be read from the disk. The provided ISO file simply sets a password for the 'ubuntu' user to 'ubuntu'. So, verification that the test worked is as easy as logging in with 'ubuntu' and 'passw0rd', either via ssh or via the console. Additionally, when the config-drive is not found, cloud-init will fall back to the EC2 data source, and block boot for several minutes as it waits. When the config-drive is found, boot will occur quickly. To perform this test, download a precise cloud-image from http://cloud-images.ubuntu.com patch it, and boot it with kvm. $ imgurl="http://cloud-images.ubuntu.com/releases/precise/release-20130124/ubuntu-12.04-server-cloudimg-amd64-disk1.img"; - $ deburl="wget https://launchpad.net/~smoser/+archive/cloud-init-test/+files/cloud-init_0.6.3-0ubuntu1.5%7Eppa1_all.deb"; + $ deburl="https://launchpad.net/~smoser/+archive/cloud-init-test/+files/cloud-init_0.6.3-0ubuntu1.5%7Eppa1_all.deb"; $ isourl="https://bugs.launchpad.net/cloud-init/+bug/1037567/+attachment/3509468/+files/disk.config.gz"; - $ wget $url -O precise-amd64.img.dist + $ wget $imgurl -O precise-amd64.img.dist $ wget $deburl -O cloud-init.deb $ wget $isourl -O cfgdisk.img.dist; $ qemu-img convert -O qcow2 precise-amd64.img.dist disk1.img.dist $ qemu-img create -f qcow2 -b disk1.img.dist patched.img.dist $ zcat --force cfgdisk.img.dist > cfgdisk.img $ chmod 600 cfgdisk.img disk1.img.dist # patch the patched.img.dist with new cloud-init $ bzr branch lp:~smoser/+junk/backdoor-image ./bi $ sudo ./bi/mount-callback-umount patched.img.dist -- \ sh -ec 'mp=$1; cp cloud-init.deb $mp/tmp && LANG=C chroot $mp dpkg -i /tmp/cloud-init.deb ; rm $mp/tmp/cloud-init.deb' -- $ qemu-img create -f qcow2 -b disk1.img.dist unpatched.img $ qemu-img create -f qcow2 -b patched.img.dist patched.img # boot patched and unpatched images $ kvm -m 512 -drive file=unpatched.img,if=virtio -drive file=cfgdisk.img,if=virtio $ kvm -m 512 -drive file=patched.img,if=virtio -drive file=cfgdisk.img,if=virtio The unpatched version will take quite a long time to boot, and you'll messages on the serial console like:see: 2013-01-31 18:53:18,185 - DataSourceEc2.py[CRITICAL]: giving up on md after 120 [Regression Potential] The potential for regression is low. The most likely possibility for error would be in incorrectly identifying a cd-rom and its content as a config-drive. == End SRU Information == ## Howto launch instance with config-drive ### nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey nova boot --key_name=mykey --image=$IMAGE \ --config-drive=1 --flavor=m1.tiny \ --user_data=./user-data.txt cfg-drive-test We need to update the config-drive datasource to support config-drive-v2 [1].
