Unable to Increase Maximum Agents in Managed DevOps Pool Despite Available Azure VM SKU Quota

Question

In the Managed DevOps pool, we've added a separate agent pool in Azure DevOps.

However, we are unable to set the "Maximum agents" value for the "Standard D2ads v5" VM size to more than 2, despite having over 100 D2ads v5 instances available in our subscription quota for the selected region.

According to the official documentation (link), it should be possible to utilize the increased quota for D2ads v5. In our case, the quota allows for up to 650 instances, yet we are still restricted to a maximum of 2 agents.

Many thanks in advance!

Hello Tomasz Mazur,

1. Your subscription quota (650 instances) applies to general VM deployments.
2. Managed DevOps Pools have their own quota tracked under the Microsoft.DevOpsInfrastructure resource provider.

Check Managed DevOps Pools quota:

• In Azure Portal: Subscriptions → Usage + Quotas → Filter by Microsoft.DevOpsInfrastructure.
• Or run: az vm list-usage --location <region> --output table
• Look for entries under Managed DevOps Pools.

If there is no available quota you need to raise Request a quota increase for Managed DevOps Pools.
