[atlas] probes on VMs

As one who supported this in the first place I think definitely should be taken up a due to cost saving and b due to power savings.

the virtual machine may affect measurement times to a extent but you need to understand that there maybe virtual routers/virtual firewalls in the network path so don’t blame just the source vm machine

also virtual probes could help to identify vm environment performance problems
