 Review comment:
   we are trying to get rid of these _'s . no need to adhere to this old 
convention. In fact you may want to rename the others as well (in a separate 
commit for review ease) (this is not a request for change, just a suggestion)

>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the 
> default.) 
>          Components: Management Server
>    Affects Versions: 4.11.0.0
>         Environment: My setup is CentOS 7 Management server with 3 CentOS 7 
> KVM HVs, NFS as primary and secondary storages.
>            Reporter: Nux
>            Priority: Major
>
> VM HA fails to kick in when one of the hypervisors goes down.
> It even fails to restart the system VMs which remain down along with the 
> instances until the affected HV comes back online.
> When I crash or power off the HV the system marks it in the hosts list as 
> "Alert" or "Disconnected" respectively. It should get changed to "Down" after 
> that, but this never happens.
>  
> I have tried various combinations of setups (Adv, Basic), none succeeded.
>  
> My instances use HA enabled offerings.
> Management server DEBUG logs here:
