> The isVmAlive() method should return null when it is unable to conclusively
> determine if the VM is alive or not.
> I ran some tests using Simulator and found that HypervInvestigator determined
> that VM is not alive. How can HypervInvestigator determine status of a VM
> running on Simulator or any other HV?
