Instance Deployment Failing for Certain AMIs in Platform9 Managed Omni

Problem

Instance deployment fails for certain images with the following error.

An error occurred (Unsupported) when calling the RunInstances operation: The requested configuration is currently not supported. Please check the documentation for supported configurations.

Environment

  • Platform9 Managed OpenStack - v3.6.0 and Higher

  • Omni

Cause

This error is observed because of different architectures associated with the flavor and the AMI. It is possible that the AMI deployed is using ARM64 and the corresponding flavor uses x86_64.

Resolution

Deploying the instance with a flavor starting from a1 ( these are backed by Arm-based AWS Graviton Processors) and testing if the instance deployment completes successfully. If it still fails, please log a ticket with the Platform9 Cloud Support team.

Additional Information
