Getting reconfigure virtual machine task continuously after vCenter Server update to 8.0 U3

Products

• VMware vCenter Server 8.0

Issue/Introduction

• vCenter continuously shows Virtual Machine reconfiguration tasks after patching vCenter Server from 8.0 U2 to 8.0 U3 latest build.
• Monitor -> Events tab on vCenter Server UI shows several events related to vCLS such as "Creating vCLS", sample screenshot pasted below:
  
  

Cause

This is caused due to vCLS VMs getting re-deployed after patching the vCenter Server.

Resolution

This is an expected behaviour after vCenter Server patching. These VMs are System Managed and will get redeployed to take new build configuration. The VM reconfiguration tasks for vCLS VMs will stop after some time once all the Clusters in the vCenter Server are configured with the new vCLS VMs and no manual intervention needed.

Refer vSphere Cluster Services (vCLS) in vSphere 7.0 Update 1 and newer versions for more information on vCLS Virtual Machines.
