Hello,
For out test environment we have a need to deploy a large number of Windows 7 VMs with customer software installed, which we run for a few days and destroy before the next build. I have been trying for a little over a week now to automate this process as much as possible via Ansible; I am able to deploy n clones of a template snapshot with no trouble, but I’m having trouble with the post-clone configurations - we need each VM to have a unique machine name, and would ideally like to make some other modifications that would normally be performed using the Customization Specification Manager in the vSphere Web Client, but per the vsphere_guest documentation it doesn’t seem that is currently possible (‘No guest customization changes to hardware such as CPU, RAM, NICs or Disks can be applied when launching from template.’).
Is there a way to perform the customization that I’m missing? If not, is that feature on the roadmap for vsphere_guest? I suspect I’m not the only one that would find it extremely useful. 
Thanks,
Daniel Carl
