Fixes #230

@d4nuu8 is there gonna be an official release for this one or it's gonna be generally available as soon as it's merged?

[lareeth]

@arcilli it's up to Microsoft as @d4nuu8 is just a external contributor

Any way to nudge this along? This would be incredibly valuable and is a real blocker to cross-architecture builds on Azure DevOps. With the rise of ARM64/AARCH64 with more and more Mac M1/M2 machines, this capability is really important to most large organisations.

[lareeth]

I would suggest emailing opensource@microsoft.com with something to the effect of

Dear Microsoft Open Source,

Please can you provide some support in prioritising a feature request for Azure DevOps, this feature request provides support for VMSS pools using ARM64 architecture. This is a important feature especially with Azure's support for ARM64 based instances, and the announcement of Server 2025 supporting ARM64.

Please can you respond to the feature request: 
Issue: https://github.com/microsoft/vsts-azurevm-extension/issues/230
Pull Request: https://github.com/microsoft/vsts-azurevm-extension/pull/232

Regards,

@mmrazik @tkasparek Hi friends. We were put in contact over email about the possibility of getting this feature moving - can you share what we need to do for that to happen? Thank you! 🙏

There is a private preview which enables arm64 agents. I guess nobody should expect this getting merged soon. I don't know why nobody from MS can write this here.

I'll keep this open anyways.

[lareeth]

@d4nuu8 Do you have any details of this private preview? As Azure DevOps installs this extension in VMSS, so I would be surprised if they had ARM64 working as this PR is required to get it working. The agent already supports ARM64 its just the extension that has this issue

[MarianSWA]

Highly anticipating this! I kinda hoped that now that Microsoft actually released arm devices they'll stop ignoring arm everywhere 😆

[mmrazik]

The preview mentioned here is/will be a different offering not based on this extension (which is the primary reason why we are not merging it). Due to various reasons the public preview got delayed so I apologize for the delay here.

@mmrazik Can you provide more information, as its been almost a year since I raised the issue, if someone had mentioned there was a private preview for an alternative to this, I could have spoken to our account manager and potentially got access to this preview, instead we had no response from anyone.

[mmrazik]

@lareeth please reach out via your account manager (or if you want drop me an e-mail -- my github handle at github.com; your account manager should be able to find me in our org-chart too). We can enable your org for private preview.

I admit we are not doing a great job with managing our code and issues on github. The official support channels for ADO are definitely via CSS and/or account managers.

[mmrazik]

This is the "next gen" of VMSS based pools:

[lareeth]

There is still value in supporting this, especially with such a small change required.

[stefankaufmann]

Quite annoying to run into this issue after creating custom images for an arm64 scale set, adding the pool to azure devops and starting a pipeline.

The fix is so small, please just merge this
