Vanilla plugin (which installs Vanilla Apache Hadoop) requires a pre-built Linux images with Hadoop, so if qcow2 does not work for bare metal, you will need to somehow build images in required format. On the other hand HDP plugin (which installs Hortonworks Data Platform), does not require pre-built images, but works only on Red Hat OSes, as far as I know.
HDP Plugin will support SUSE, Debian in the future, but for now HDP only provides pre-built CentOS images.

Mainly authentication with keystone, basic operations with VMs via nova (create, list, terminate), basic operations with images (list, set/get attributes). Snapshots are not used. That is for basic functionality. Other than that, some features might require additional API calls. For instance Cinder support naturally requires calls for volume create/list/delete.
