Governance and Maintainers
Note: this section may be augmented by the completion of a Governance Review from TAG Contributor Strategy.
Suggested
- [x] Governance has continuously been iterated upon by the project as a result of their experience applying it, with the governance history demonstrating evolution of maturity alongside the project's maturity evolution.
In the past 12 months we have formalised our usage of SIGs and introduced KubeVirt working groups and subprojects. We have also added documentation around inactive members, and expanded on our maintainer responsibilities:
- https://github.com/kubevirt/community/pull/298
- https://github.com/kubevirt/community/pull/301
- https://github.com/kubevirt/community/pull/306
- https://github.com/kubevirt/community/pull/365
- https://github.com/kubevirt/community/pull/366
Required
- [x] Clear and discoverable project governance documentation.
Our governance doc and our membership policy are in the root of our community repo. These are also linked to from the README, and in the user guide contributing page.
- [x] Governance is up to date with actual project activities, including any meetings, elections, leadership, or approval processes.
Our governance doc and membership policy explain the domains of the maintainers, SIGs, WGs, and Subprojects, as well as our contributor ladder to grow into a reviewer, approver, SIG/WG/Subproject Chair/Lead, and maintainer role. SIG meetings are captured in the charters for each SIG and in our sigs.yaml file in our community repo, linked to from the governance doc.
- [ ] #381
- [x] Document how the project makes decisions on leadership roles, contribution acceptance, requests to the CNCF, and changes to governance or project goals.
Leadership roles Our membership policy defines the leadership roles, responsibilities, and criteria with links where applicable.
Contribution acceptance The contribution acceptance is at the discretion of the repo approvers or SIG/WG/subproject chair/lead as described in our membership policy
CNCF requests Any maintainer may suggest a request for CNCF resources, in the developer mailing list, the maintainer mailing list, on Github, or during a community meeting. A simple majority of maintainers approves the request. The maintainers may also choose to delegate working with the CNCF to non-maintainer community members.
Changes to governance Most votes require a simple majority of all maintainers to succeed. Changes to Governance requires a 2/3 maintainer vote.

[ ] #382
- [x] Release expectations (scheduled or based on feature implementation)
- [ ] Tagging as stable, unstable, and security related releases
- [x] Information on branch and tag strategies
- [x] Branch and platform support and length of support
- [ ] Artifacts included in the release.
- Additional information on topics such as LTS and edge releases are optional. Release expectations are a social contract between the project and its end users and hence changes to these should be well thought out, discussed, socialized and as necessary agreed upon by project leadership before getting rolled out.
- Release expectations: we have a public schedule in our sig-release repo. We check in with the current release schedule every week during our community meeting.
- Tagging: TODO
- Information on branch and tag strategies: These strategies are details in our release document.
- Branch and platform support: We have a release document that details our versioning and support. We also maintain a support matrix which is linked to in our release tag notes, as well as our kubevirt and community readmes and our release notes.
- Artifacts included in release: TODO
- [x] History of regular, quality releases.
From 2017 to 2022, KubeVirt would release on a monthly cadence, with an RC approximately 10 days prior to release to ensure a tested, quality release. Since October 2022, the project moved to a tri-annual release, following in lock-step with the Kubernetes release; with this change we now have a three-week period of testing, with alpha, beta, and at least one RC prior to the release.
This history can be found on our releases page of kubevirt/kubevirt: https://github.com/kubevirt/kubevirt/releases Our release schedules can be found on our sig-release repo: https://github.com/kubevirt/sig-release/tree/main/releases Our release notes can be found in our user guide (and in the release tag): https://kubevirt.io/user-guide/release_notes/

- [ ] #337
- [ ] #336
- [ ] #335
-
[ ] Third Party Security Review.
- [ ] Moderate and low findings from the Third Party Security Review are planned/tracked for resolution as well as overall thematic findings, such as: improving project contribution guide providing a PR review guide to look for memory leaks and other vulnerabilities the project may be susceptible to by design or language choice ensuring adequate test coverage on all PRs.
- [x] Achieve the Open Source Security Foundation (OpenSSF) Best Practices passing badge.
The project has a passing badge since 2021. It was comprehensively updated on 2024-04-12 15:48:53 UTC. The passing badge is visible on our kubevirt/kubevirt readme.
Ecosystem
Suggested
N/A
Required
- [x] Publicly documented list of adopters, which may indicate their adoption level (dev/trialing, prod, etc.)
Our adopter list is visible in our kubevirt/kubevirt repo and contains 32 adopters: https://github.com/kubevirt/kubevirt/blob/main/ADOPTERS.md
- [x] Used in appropriate capacity by at least 3 independent + indirect/direct adopters, (these are not required to be in the publicly documented list of adopters)
The project provided the TOC with a list of adopters for verification of use of the project at the level expected, i.e. production use for graduation, dev/test for incubation.
- [ ] TOC verification of adopters.
Refer to the Adoption portion of this document.
- [ ] #338
Adoption
Adopter 1 - $COMPANY/$INDUSTRY
If the Adopting organization needs to remain anonymous, stating the industry vertical is sufficient. MONTH YEAR
Adopter 2 - $COMPANY/$INDUSTRY
If the Adopting organization needs to remain anonymous, stating the industry vertical is sufficient. MONTH YEAR
Adopter 3 - $COMPANY/$INDUSTRY
If the Adopting organization needs to remain anonymous, stating the industry vertical is sufficient. MONTH YEAR
@aburdenthehand Few minor notes while proofreading this:
- Adoption Assertion - missing link to the adopters file (I don't know why this is required as there is a whole section on Adoption, but better to add it there).
- Demonstrate contributor activity and recruitment - Add there a link to kubevirt devstats, so they don't need to search for it :)
Other than that, it looks like it'll be soon ready to go.
