Quick Recap

The meeting focused on reviewing Mie's progress on Windows 11 and ARM support for their project. Mie reported completing Windows 11 architecture support but still needs to work on Windows 11 ARM architecture support and address review comments. Akihiro suggested implementing provision features as the primary goal, with file system sharing and port forwarding being optional enhancements that could be deferred. The team discussed testing Windows 11 ARM64 support on Mac OS, with Mie offering to borrow a Mac computer from a family member to test the code. They also clarified that Mie should take commits from an existing PR rather than waiting for Jan's separate work on SIGPAS cygpath. The discussion included explanations of port forwarding functionality and its use cases, particularly for accessing Docker containers running in Windows guests. Akihiro mentioned plans to include Windows 11 ARM64 support in version 2.2, which will be released before CubeCon KubeCon, and noted that work on removing SIGPAS cygpath dependency would be expected in August.

Next Steps

• Mie: Address review comments from Akihiro regarding Windows 11 architecture support this week.
• Mie: Implement the provision feature this week.
• Mie: Test the code on a Mac OS computer (borrow from family member) and share the results with the team.
• Mie: Take some commits from the existing PR for SIGPAS cygpath dependency, review, test, and sign off the code.
• Mie: Investigate and decide between Hyper-V and HCS for the native driver on Windows.
• Akihiro: Try running Windows 11 ARM64 on his Mac and share the results.
• Akihiro: Postpone the meeting scheduled for the holiday in Japan to Tuesday or Wednesday.

Summary

Windows 11 and ARM Support:
Mie reported progress on Windows 11 and AMD/ARM support, completing Windows 11 architecture support but still needing to work on ARM architecture implementation. Akihiro suggested Mie implement provisioning features first, with file system sharing and port forwarding being optional advanced features. The team discussed testing Windows 11 support on Mac OS, with Akihiro confirming it should work but would be slow due to emulation (for running x86_64 on ARM), and Mie agreed to test the code on a family member's Mac computer and share the results.

SIGPAS cygpath and Pavilion Compatibility Discussion:
Mie discussed moving to a new topic and asked for comments, with Ansuman noting that Mac compatibility would make it easier to showcase their pavilion. Mie then inquired about SIGPAS cygpath dependency, referencing a previous discussion where Jan mentioned continuing work on the sick bus and creating a separate PL PR for mentorship purposes.

AI Code Review Process Clarification:
Akihiro clarified that Mie doesn't need to wait for Jan's work and can take commits from an existing PR, review and test the code, and sign off on it since it was generated using AI. Mie expressed interest in understanding the port forwarding feature, which Akihiro confirmed was not a requirement.

BIMA Lima Port Forwarding Discussion:
Mie asked about utilizing port forwarding in the BIMA Lima environment, and Akihiro explained how it works with DNUCs Linux and provided an example of running a Docker container. Ansuman suggested focusing on file sharing implementation rather than port forwarding for now, as the Virtio FS implementation might take more time. The team agreed to defer the port forwarding work, with Akihiro noting that it could be revisited later when native drivers for Windows hosts are available.

Windows 11 ARM64 Development Planning:
Akihiro discussed plans to include Windows 11 ARM64 in version 2.2 and work on zip commit for removing sigfast cygpath dependency, with Mie confirming understanding of the two-week timeline. Akihiro explained upcoming meeting schedules, noting that the regular monthly meeting would be held next week, followed by a weekly meeting, and then postponed to Tuesday or Wednesday due to a Japanese holiday. The meeting on the 27th was cancelled due to its proximity to KB4 KubeCon in Japan, and the group agreed to reschedule the postponed meeting to July 22nd, which was confirmed to work for all participants.
