Environment

VMware vCenter Server 

 

Cause

A solution requires that an agent VM be on the host. If there are any issues with the agency/solution and/or its no longer in use, this can cause issues with powering on a VM. 

Resolution

  1. Login to the vSphere Client UI 
  2. Click on the hamburger menu button 
  3. Click Administration > vSphere Client Extensions > VMware ESX Agent Manager > Configure 
  4. Resolve any agencies that are required or remove any that are no longer needed
