Subject [jira] [Commented] (CLOUDSTACK-7932) [Hyper-V] Wrong semantics for isVmAlive() method in HypervInvestigator

    No. Because agent is reporting status of host. We cannot determine the status of VMs from
that.

> 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?
