  • Waiting for PR https://github.com/mie313/lima/commits/hcs-driver/
    • qcow2-to-vhdx conversion should not depend on qemu-img.exe
      • https://learn.microsoft.com/en-us/windows/win32/api/virtdisk/nf-virtdisk-createvirtualdisk may return a writable file handle? If not, use https://learn.microsoft.com/en-us/windows/win32/api/virtdisk/nf-virtdisk-attachvirtualdisk
      • Go library: https://pkg.go.dev/github.com/Microsoft/go-winio/vhd
      • Can be worked out after submitting the PR

Quick Recap

Akihiro and Mie conducted a progress review meeting where Mie presented her work on implementing the HCS driver for Windows host over the past two weeks. Mie demonstrated the driver functionality by showing how she could start, share, and stop VMs using LimaCTL with HCS folders driver on Lima. During the demo, they encountered connectivity issues with DNS resolution that caused delays and failed package updates, which Akihiro helped troubleshoot by identifying a configuration problem with resolver CTL resolvectl settings. Mie also mentioned needing to write a blog post or report for her internship program, with a due date of the following day, and discussed the format requirements with Akihiro and Ansuman. The conversation ended with confirmation that the next online session would be held the following week on August 31st.

Next Steps

• Mie: Write test code and raise the 1st PR for the HCS driver implementation as is.
• Mie: Investigate and fix the DNS configuration issue in the HCS driver, and update the code today.
• Mie: Write and submit a blog post/report for the CNCF internship program by tomorrow, using a personal blog platform.
• Mie: Prepare for the first demo session scheduled for August 31st.

Summary

HCS Driver Implementation Progress:
Mie reported implementing the HCS driver for Windows host over the past two weeks, allowing LimaCTL start, share shell, and stop functions to work with HCS folders driver on Lima. She plans to write test code and raise a PR this week, with Akihiro suggesting she can address the QEMU image issue later. The conversation ended with Akihiro requesting a demo from Mie.

VM HGS HCS Driver Demonstration:
Mie demonstrated running a VM using HGS HCS driver and successfully stopped and restarted it. She then connected to the VM via Lima CTL shell and confirmed she could enter the VM. Akihiro requested to see an IP command and suggested shrinking the command prompt window to better view the screen.

Fedora Connectivity Issue Diagnosis:
The team discussed connectivity issues Mie was experiencing while using Fedora on Windows. They tried various diagnostic commands including ping and DNS lookup tests, determining that while internet connectivity was working, there appeared to be a DNS configuration issue. Akihiro suggested it might be an SSH configuration problem, and they discussed the possibility of restarting the system as a potential solution.

Configuration Issue Investigation Meeting:
Akihiro asked Mie to investigate a configuration issue and show the configuration inside a gist, mentioning the specific resolver CTL resolvectl version 1.2168543 (hallucination ?). Mie agreed to investigate the issue and update the code that day. Mie also mentioned realizing the need to write additional code, though the specific details were not completed in the transcript.

CNCF Blog Submission Discussion:
Mie discussed submitting a blog post or report due tomorrow to CNCF, and Akihiro clarified that mentees typically use their personal blogs, suggesting Mie could use an existing platform like Medium. The next online meeting was confirmed for August 31st, which will be the first demo session. No additional questions or topics were raised by any participants.
