 You can check, on all hosts, /var/log/ovirt-hosted-engine-ha/* .

It seems to work quite well, but after some hours I get many status
update
mails from the ovirt engine which are either going to EngineStop or
EngeineForceStop. Sometimes the host where the engine runs is switched.
After some of those reboots there is silence for some hours before it is
starting over. Can you tell me where I should look at to fix that
problem?

thanks, that helped. Our gateway does not always respond to ping-requests so
I changed the penality score accordingly.


How? In the code?
I changed the value for "gateway-score-penalty" in 
/etc/ovirt-hosted-engine-ha/agent.conf .

How? In the code?

I am not sure there isn't some other logic that relies on this score,
such as wishing to migrate away the engine VM from its host if it fails
this specific test.

Thanks for the report!

thanks, that helped. Our gateway does not always respond to 
ping-requests so I changed the penality score accordingly. It is now 
running stable for almost one week.
