If you have provisioned a Tanzu Kubernetes cluster, but the control plane virtual machines do not start, you might need to change the virtual machine size or class.

Problem

You have provisioned a Tanzu Kubernetes cluster. The system is attempting to power on the control plane virtual machine(s), but it errors out with the following message:

The host does not have sufficient CPU resources to satisfy the reservation.

Cause

The virtual machine size or class is not sufficient for the cluster deployment.

Solution

Change the virtual machine type or class. See Virtual Machine Class Types for Tanzu Kubernetes Clusters.
