Hi list!

I'm new by oVirt. Right now I configured a Cluster with two hosts and a VM.
I can migrate the VM between the two hosts without any problem, but what I need 
is, that the VM automatically migrate if an host is down.

The migration occurs just if I set an host in "Maintenance", but this is not 
(only!) what I need...

Can someone help me to configure oVirt (3.5) to automatically check the hosts 
and migrate the VM on host failure?

Thanks a lot!

Mit freundlichen Grüßen

You can't live migrate on a host failure - as the host has gone down and all the running VMs on it have as well! It would require clairvoyance to enable live migration in that situation.

However you can enable HA in VMs. If the host they are running on fails they will be restarted automatically on another host. NB. This *requires* power management so the failed host can be fenced.
