Agenda

Note taker: @AkihiroSuda

v2.1.x

• v2.1.2 planning (for Ubuntu 26.04) #4814
  • Ubuntu 26.04 ETA: Apr 23
  • Maybe ship v2.1.2 without updating Ubuntu 26.04, and then v2.1.3 with Ubuntu 26.04? Probably not worth doing so
    • https://github.com/containerd/containerd/releases/tag/v2.2.3 : spdystream CVE-2026-35469
      • Unlikely exploitable unless kube-apiserver is open to untrusted users

PR reviews

https://github.com/lima-vm/lima/pulls

• Fix race condition in 04-persistent-data-volume.sh #4831

  • Draft, as needs testing. @jandubois will test it by the next week

• Krunkit: support SSHOverVsock and replace SSH-based guestagent connection with vsock #4822

  • Should improve SSH performance
  • Seems mergeable

• feat(macos): implement guest agent daemon and support for port forwarding #4774

  • Still draft, failing CI

• feat(templates): add amazonlinux-2023 distro #4454

  • Seems ready to merge
  • @AkihiroSuda will test before merging

v2.2? v3.0?

• Windows guest/host
  • Guest
    • vz cannot be supported due to lack of TPM
    • Use autounattend.xml instead of cloud-init
  • Host
    • Improve stability
      • "Manual Validation ended with the VM in an unusable state. This package is very large, and consumes more than 20 GB during the Scan step." New Package: Add Lima.Lima v2.1.1 microsoft/winget-pkgs#356038 (comment)
      • WSL2 driver: only works with Finch image, only runnable a single instance (SSH port is hard-coded)
    • Reduce dependency (e.g., cygpath.exe) Windows: drop dependency on cygpath.exe, MSYS2, Git for Windows, etc. #4819
    • Add Hyper-V VM driver
      • Probably needs a Pro? Enterprise? license
    • QEMU should be the most recommended driver for a while. Hyper-V will be probably eventually the best driver (for Enterprise)
    • limagui.exe ?
  • Do we want to apply for LFX Mentorship?

LFX Mentorship

https://github.com/cncf/mentoring/tree/main/programs/lfx-mentorship/2026/02-Jun-Aug

• Schedule:

  • Apr 1 - Apr 28: Project proposals Open
  • May 4 - May 19: Mentee applications Open
  • May 20 - Jun 2: Review period
  • Jun 8 - Aug 31: Program term (Evaluations: Jul 21, Aug 25)

• @AkihiroSuda may not have a bandwidth in the weeks of Apr 28 and May 4

  • @unsuman will help drafting a proposal statement

klimax

• https://github.com/bcollard/klimax by @bcollard

klimax is an dependency-free CLI that manages a macOS Virtualization.framework (VZ) Lima VM, installs Docker inside it, creates and manages multiple kind clusters, and wires up pure L3 routing from your Mac into the kind bridge subnet — no SNAT, no VPN, direct IP access to pods and LoadBalancer services.

• The name ("lima" substring in "klimax") seems ok from perspective of maintainers (legal questions should be asked to CNCF/LF)
  • Lima is not a registered trademark
  • We have been already allowing colima

Tasks

• @AkihiroSuda release v2.1.2 with Ubuntu 26.04
• @jandubois test his draft PR Fix race condition in 04-persistent-data-volume.sh #4831
• @AkihiroSuda test feat(templates): add amazonlinux-2023 distro #4454 before merging
• @unsuman draft a proposal statement for LFX Mentorship

2026-05-21 (Thursday) Conflicts with Open Source Summit North America

2026-05-14 (Thursday)?
2026-06-18 (Thursday)?

[jandubois]

@bcollard One thing I forgot to mention: we don't make any stability / compatibility guarantees for the Lima Go packages, so any Lima update may break your project, and it will be up to you to detect and adjust for that. There are no public APIs at the Go level for Lima. We don't hide our packages in an internal tree, but usage is at your own risk.

We only provide backward compatibility at the limactl and lima.yaml level.

[bcollard]

understood, and makes sense! got to work on CI.
thanks for the heads up!

AI-generated meeting note

Quick Recap

The meeting focused on discussing the release plan for version 2.1.2 and potential support for Windows guests in version 2.2 or 3.0. Akihiro outlined plans to release version 2.1.2 after Ubuntu 22.04, while Jan mentioned an ongoing PR for Alpine that addresses an issue seen by multiple users. The team discussed Windows guest support requirements, including the need for QEMU NetBZ, alt-r-attent.xml, and improved host stability with dependencies like sigpass.exe and drivers for WSA2 and GME. They also explored the possibility of applying for Linux Foundation mentorship, with Ansuman offering to help draft a proposal. Baptiste shared information about creating a CLI tool using Lima Go packages for managing VM lifecycle, and received approval for the naming from the team. The next meeting was discussed, with a potential change from May 21st to May 14th due to a scheduling conflict with Open Source Summit North America.

Next Steps

• Jan: Complete testing of the PR for the Alpine issue and aim to have it ready for 2.1.2 by next week.
• Akihiro: Check and try merging the Amazon Linux PR before the 2.1.2 release.
• Ansuman: Draft a statement/idea for the Linux Foundation mentorship program by the end of this week.
• Akihiro: Change the next meeting schedule to May 14th (or confirm new date), avoiding conflict with Open Source Summit North America.

Summary

Version 2.1.2 Release Planning:
Akihiro discussed the release plan for version 2.1.2, considering the release timeline after Ubuntu 6.04. Jan mentioned having a PR in progress for Alpine that addresses an issue, which still needs testing but could be included in version 2.1.2. The team determined that a release for the recent SpiderMonkey vulnerability fix was not necessary as it is not directly exploitable without additional vulnerabilities.

Version 2.1.2 and 2.2 Planning:
The team discussed merging several items for version 2.1.2, with Jan indicating that testing was still needed but hoping to have it ready by next week. Akihiro mentioned that Amazon Linux support was ready to merge, noting differences in its implementation compared to other systems. The discussion then shifted to planning for version 2.2, where they explored supporting Windows guests using QEMU NetBZ, which requires alt-r-attent.xml for Windows setup and specific host dependencies including sigpass.exe and drivers for WSA2 and GME.

Driver and Image Consolidation Discussion:
Jan and Akihiro discussed the current state of drivers and images for different platforms. They identified issues with the WSL driver, including its limited functionality and dependency on specific SSH libraries. The conversation focused on the need to consolidate templates and images for different platforms, such as QEMU and WSL, into a more unified approach. They also touched on the potential benefits of using Hyper-V for Windows hosts, though Jan noted some requirements around Windows versions.

Linux Foundation Mentorship Program Proposal:
Akihiro proposed applying for Linux Foundation mentorship program for Rangers project, with a deadline of April 28th. Jan and Anders indicated they couldn't participate, but Ansuman offered to help and committed to drafting a proposal statement by the end of the week. The team discussed potential project ideas, with Akihiro suggesting work on Hyper-V driver and KIST support as possible areas for the mentorship program.

CLI Tool Naming Approval Discussion:
Baptiste sought approval for using the name "Lima" for his CLI tool that helps run Kind clusters on VMs. Akihiro and Jan confirmed there were no trademark issues with the name, as long as it's not used alone as a project name. The next meeting was rescheduled from May 21st to May 14th due to a conflict with the Open Source Summit North America, with a potential alternative of June 18th if May 14th doesn't work for everyone.

Corrections

Akihiro outlined plans to release version 2.1.2 after Ubuntu 22.04

22.04 → 26.04

The team discussed Windows guest support requirements, including the need for QEMU NetBZ, alt-r-attent.xml, and improved host stability with dependencies like sigpass.exe and drivers for WSA2 and GME.

NetBZ → "not vz"
alt-r-attend.xml → autounattend.xml
sigpass.exe → cygpath.exe
WSA2 → WSL2
GME → QEMU (?)

SpiderMonkey → spdy

I don't think we have talked about SSH libraries.

What is "Rangers"?

KIST → (Windows) guest (?)
