Root Cause

Azure enforces regional vCPU quotas per VM family; attempting to deploy a VM that exceeds the available quota fails.

generic

中文

Azure 对每个VM系列实施区域vCPU配额；尝试部署超出可用配额的VM会失败。

Workarounds

  1. 80% success Submit a quota increase request via Azure portal: go to Subscriptions > Usage + quotas > select VM family > Request increase. Example: request 20 vCPUs for Standard DSv3 Family. 
    Submit a quota increase request via Azure portal: go to Subscriptions > Usage + quotas > select VM family > Request increase. Example: request 20 vCPUs for Standard DSv3 Family.
  2. 70% success Deploy to a different region with available quota using `az vm create --location <region>`. 
    Deploy to a different region with available quota using `az vm create --location <region>`.
  3. 60% success Use Azure Spot VMs which draw from a separate quota pool, if applicable.

中文步骤

  1. 通过Azure门户提交配额增加请求：转到订阅 > 使用量+配额 > 选择VM系列 > 请求增加。例如：为Standard DSv3系列请求20个vCPU。
  2. 使用`az vm create --location <region>`部署到有可用配额的其他区域。
  3. 如果适用，使用Azure Spot VM，它们使用独立的配额池。

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Deleting VMs frees quota but may cause downtime; also, the quota limit is per region and family, so deletion only helps if you're at the cap.

  2. 70% fail

    The quota is per VM family (e.g., DSv3), not per size; all sizes in the family consume the same vCPU count as their specification.

  3. 80% fail

    You need to request an increase for the specific family and region you're deploying to, not a different one.
