How to get VC:VirtualMachine from a vcac blueprint

I was trying to follow this guide below to create a workflow to be executed from a vcac blueprint.. Basically i took the template Vcac/infrastructure administrator/Workflow Template

which has this piece of code

if (vCenterVm != null) {

  System.log("Got vCloud VM " + vCenterVm.name);

}

Well, it never prints the vm name. I need it in order to run operations on the vm after the vm is deployed .. how am i able to get it .. and why would the template have it if it's

not availabl.e
