This KB article outlines a change in the behavior of performance chart displays between versions 7. Workaround: 1. Wait 2 minutes for the vCLS VMs to be deleted. vCLS VM placement is taken care of by the vCenter Server, so user is not provided an option to select the target datastore where vCLS VM should be placed. If all goes good, you are good to delete the folders, otherwise move back files to. Building on the installation and configuration content from our best-selling course, you will also develop advanced skills needed to manage and maintain a. When vCLS VMs are being deployed, they are created in a folder called "ESX Agents" instead of the default vCLS folder that stays empty. As I have a bunch of questions about how you can delete the vSphere Cluster Service VMs (vCLS VMs) I figured I would create a quick demo. Smarter Affinity Using the Compute Policies construct which now is part of vSphere, we can enforce smarter agent. Since vCLS VMs are deployed as soon as a first host is added to a new cluster, any test scripts to validate empty cluster in a greenfield deployment should have to be change.
