LFX Mentorship

• [LFX Mentorship] Improve Windows support (guest and host) #4907

✅Work done on 21st July:

• Investigated HCSShim
• Started trying to launch VM on my Windows local
  • Added my user account to 'Hyper-V Administrators' group
  • Write codes to create a VM using HCSShim

🎯Goals for tomorrow:

• Continue trying to create a VM on my Windows local
• Address review comments on a PR Support provision feature on Windows VM #5263 (after being reviewed.)

Windows guests

• Support provision feature on Windows VM #5263

Windows hosts

• Windows: autoappend %PROGRAMFILES%\QEMU etc. to %PATH% #4820
  • This has been part of [LFX Mentorship] Improve Windows support (guest and host) #4907 since the begining
  • Not urgent, but this can be just a single-PR (just add QEMU dir to PATH)
  • HCS is more important anyway
• Support for Windows hosts, without depending on QEMU #4961
  • Using WIndows Home edition
  • Trying to implement a HCS code using Go
    • move internal/computecore out of internal microsoft/hcsshim#2825 can be used to call HCS from Go

Quick Recap

Mie provided an update on her work, reporting that she completed Windows guest-related tasks last week and has started investigating Windows host support by learning HCS SIM SHIM following Sudarsan's Akihiro Suda's advice. Akihiro asked about Mie's Windows edition and whether she had successfully run a virtual machine using HCS, to which Mie responded that she was using Windows Home and had not yet completed the code to test VM creation. Akihiro suggested using a specific PR for Go API implementation and offered support through Slack for writing the code. When Mie asked about prioritizing issue #4820 versus HCS work, Akihiro confirmed that issue #4820 should be does not need to be prioritized as although it relates to primary test synthesis and seamless Windows host installation, clarifying that automatic detection refers to Dima Lima detecting the path and requiring only a few lines of changes. The next meeting was scheduled for August 3rd.

Next Steps

• Mie: Complete the code to create a VM on Windows host using HCS, and test it.
• Mie: Update the Lima code to support creating a VM on Windows host with HCS instead of QM QEMU.
• Mie: Prioritize working on the HCS issue over issue 4820. (No need to be prioritized, but it should be quite easy to complete)
• Mie: Address issue 4820 by implementing automatic detection of the specified path, as clarified by Akihiro.
• Akihiro: Provide review comments on the proposing feature.

Summary

Windows Host Support Progress Update:
Mie reported that she completed Windows guest work last week and has started investigating Windows host support by learning HCS SIM SHIM following Sudarsan's Akihiro Suda's advice. She is currently working on creating a VM with HDS SIM HCS SHIM on her local PC and plans to update the Lima code to support VM creation on Windows host with HCS. Akihiro inquired about Mie's Windows edition and whether she successfully ran a virtual machine using HCS, to which Mie responded that she hasn't completed the code yet and needs to check once finished.

Golang Tutorial Implementation Discussion:
Akihiro asked Mie if she tried the tutorial code from Microsoft's website and whether it worked. Mie confirmed she referred to it but is still struggling with writing Golang codes. Akihiro suggested using a PR he created to export the Go API, which is not merged yet but can be used to create virtual machines.

Priority Task Issue 4820 Discussion:
Akihiro advised Mie to prioritize issue number 4820 over the HCS work, explaining that it relates to primary test synthesis focused on delivering a seamless installation experience on Windows hosts through automatic configurations. Akihiro confirmed this task is trivial and can be addressed alongside the HGS HCS work.

Code Recognition Feature Discussion:
Mie sought clarification about what "automatically recognize" (of QEMU binary path) meant in an issue and received explanation from Akihiro that it should be detected by Dima Lima through a simple change to the code. Akihiro indicated the fix would require only a few lines of changes and promised to review the proposed feature. The next meeting was scheduled for August 3rd.
