I want to schedule running 3 instances of same test on 3 seperate VMs, 1 after another. How can I do that?

I want to schedule run on 3 QA VMs from ALM. So in test lab, I start the execution of UFT script on VM1. Once the scripts is done on VM1, I want to run the same Script on QA VM2. How can I start the execution of that script on VM2 once it is done on VM1 automatically?
