Currently nodepool is defaulting to the qcow2 if no format was given in the diskimage config. However nodepool also can auto-detect the image format based on clouds.yaml. This is not taken into account leading to qcow2 added when using raw-only clouds and auto-detection. This can be fixed by delaying the fallback to the point where we actually do the build.

Nodepool
Nodepool is a service used by the OpenStack CI team to deploy and manage a pool of devstack images on a cloud server for use in OpenStack project testing.
Developer setup
Make sure you have pip installed:
Install dependencies:
sudo pip install bindep
sudo apt-get install $(bindep -b nodepool)
mkdir src
cd ~/src
git clone git://git.openstack.org/openstack-infra/system-config
git clone git://git.openstack.org/openstack-infra/nodepool
cd nodepool
sudo pip install -U -r requirements.txt
sudo pip install -e .
If you're testing a specific patch that is already in gerrit, you will also want to install git-review and apply that patch while in the nodepool directory, ie:
Create or adapt a nodepool yaml file. You can adapt an infra/system-config one, or fake.yaml as desired. Note that fake.yaml's settings won't Just Work - consult ./modules/openstack_project/templates/nodepool/nodepool.yaml.erb in the infra/system-config tree to see a production config.
If the cloud being used has no default_floating_pool defined in nova.conf, you will need to define a pool name using the nodepool yaml file to use floating ips.
Export variable for your ssh key so you can log into the created instances:
Start nodepool with a demo config file (copy or edit fake.yaml to contain your data):
All logging ends up in stdout.
