Greetings, Nova includes various compute drivers today, but the test coverage they receive varies quite a bit. This is documented on the following wiki page. The drivers are broken up into groups A, B, and C. https://wiki.openstack.org/wiki/HypervisorSupportMatrix We have two new compute drivers in the queue for Havana: docker [1] and z/vm [2]. I'd like to propose as a piece of criteria for inclusion that new drivers go into groups A or B. Further, I would like to see *all* drivers move into groups A or B by the release of Icehouse. I've been told that this is already in the works for VMware and baremetal, at least. I feel like if there isn't enough interesting and willingness to raise the bar on testing a given compute driver, then we're just wasting our time and effort having it in the tree. Feedback welcome! Thanks, [1] https://blueprints.launchpad.net/nova/+spec/new-hypervisor-docker [2] https://blueprints.launchpad.net/nova/+spec/zvm-plugin -- Russell Bryant
