A few weeks ago, we introduced the Xen Project – OpenStack CI Loop, which is testing Nova commits against the Xen Project Hypervisor and Libvirt. Xen Project community is pleased to announce that we have moved from Quality Group C to B, as we’ve made significant progress in the last few weeks and the Xen Project CI loop is now voting on Nova commits.
This diagram shows the number of OpenStack Nova drivers for Hypervisors, which allow you to choose which Hypervisor(s) to use for your Nova Deployment. Note that these are classified into groups A, B and C. Xen Project is now in Quality Group B.
- Group C: These drivers have minimal testing and may or may not work at any given time. Test coverage may include unit tests that gate commits. There is no public functional testing.
- Group B: Test coverage includes unit tests that gate commits. Functional testing is provided by an external system (such as our CI loop) that do not gate commits, but advises patch authors and reviewers of results in OpenStack Gerrit.
- Group A: Test coverage includes unit tests and functional testing that both gate commits.
What does this mean in practice?
The easiest way to understand what this means in practice, is to look at a real code review as shown in the figure below.
This diagram shows how the functional tests for the Xen Project initially failed, and passed after a new patch was uploaded.
This diagram shows the status after a new patchset was uploaded. Note that the review of the patchset is still pending manual review.

Relevant Regular Meetings
Note that there are also weekly Third Party CI Working Group meetings for all operators of 3rd party CI loops in #openstack-meeting-4 on Wednesdays at 1500/0400 UTC alternating organized by Kurt Taylor (krtaylor). Third party CI operators interested in enhancing documentation, reviewing patches for relevant work, and improving the consumability of infra CI components are encouraged to attend. See here for more information on the working group.
