So you are asking how to populate array of properties given a list of VC:VirtualMachine objects?
Should be something like
parameters = new Array(); // array of properties
for (var i = 0; i < numberOfVMs; i++) { var wfInputProp = new Properties(); wfInputProp.put("nameOfInputParam", objVM[i]); // ... put other inputs if needed by your custom wf parameters.push(wfInputProp);
}
