This account may not have enough CPU cores to start a cluster. Contact your administrator to increase the limits.

    Hi Durga,

    Thanks for your post. Before moving on, to narrow down the issue, can I know if the cluster creation fails with a message about a cloud provider error when you hover over cluster state?

    Cloud Provider Launch Failure: A cloud provider error was encountered while setting up the cluster.

    If so, generally speaking, Azure subscriptions have a CPU core quota limit which restricts the number of CPU cores you can use. This is a hard limit. If you try to start a cluster that would result in your account exceeding the CPU core quota the cluster launch will fail.

    As a solution, you can either free up resources or request a quota increase for your account.

    • Stop inactive clusters to free up CPU cores for use.
    • Open an Azure support case with a request to increase the CPU core quota limit for your subscription.

    Best Regards,

    Ian Xue
