[ovirt-users] Self-hosted engine won't start

Tue Jul 29 08:52:13 EDT 2014

Hi John,
thanks for the logs. Seems like the engine is running on host2 and it 
decides that it doesn't have the best score and shuts the engine down 
and then neither of them want's to start the vm until you restart the 
host2. Unfortunately the logs doesn't contain the part from host1 from 
2014-07-24 09:XX which I'd like to investigate because it might contain 
the information why host1 refused to start the vm when host2 killed it.

Regards,
Jirka
