@yvsubhash getVm() raises CloudRuntimeException if Vm is not found.
Scenario:
Deploy a vm and ensure its in running state.
Take a VM snapshot ( either disk or disk + memory ) for VM.
After snapshot operation is sucessful , destroy the VM.
Observation :
VM destroy Fails with reason VM with name: i-2-7-VM does not exist.
SNapshot moves to Expunging state , and VM moves to stopped state.
Solution : Place your changes within a try.. catch block
