[ovirt-users] Latency threshold between Hosted Engine and Hosts

[Piotr Kliczewski]

Fernando,

We use heartbeats to understand health of the connection. Potentially
you may see heartbeat exceeded exceptions
so you may want to increase vdsHeartbeatInSeconds. I would not change
it in advance but as you see the issue
and slowly increase the value.

Thanks,
Piotr
