 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)

>          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:
> [http://tmp.nux.ro/CW4-vmhafail-411rc1.txt]
