If the latest outage was not long ago, you could still find some
preliminary and useful information inside /var/log/ovirt-engine/engine.log
of the engine
In general, for all oVirt related log files you can refer to this url:
https://www.ovirt.org/documentation/administration_guide/#chap-Log_Files
some of them are also rotated

Thank you Gianluca for your answer.
Population of /etc/hosts as a backup with host and ovirt engine ip:
this has already been done.

Fedele, I think you should define better what "misaligned" means in your case, 
give some details on versions in play, architecture (self hosted vs standalone 
engine) and provide some logs from the engine and hosts (preferably through a 
link to a file sharing service if big), so that you can get better help.

Possibly the ovirt hosts "know" each other only through a DNS server that
is not local to your infrastructure, but external on the internet?
If this is the case you can populate also their /etc/hosts as a backup
strategy, orconfigure an internal DNS server...
Just a guess
