All these are irrelevant.

The only relevant error is:

2016-09-26 03:00:42 DEBUG otopi.plugins.otopi.services.rhel
plugin.executeRaw:828 execute: ('/sbin/service', 'ovirt-engine',
'start'), executable='None', cwd='None', env=None
2016-09-26 03:00:43 DEBUG otopi.plugins.otopi.services.rhel
plugin.executeRaw:878 execute-result: ('/sbin/service',
'ovirt-engine', 'start'), rc=1
2016-09-26 03:00:43 DEBUG otopi.plugins.otopi.services.rhel
plugin.execute:936 execute-output: ('/sbin/service', 'ovirt-engine',
'start') stdout:
Starting oVirt Engine: [FAILED]

2016-09-26 03:00:43 DEBUG otopi.plugins.otopi.services.rhel
plugin.execute:941 execute-output: ('/sbin/service', 'ovirt-engine',
'start') stderr:

So we need engine logs to know more.

If none were generated, it might have failed too early.

Please check system logs - /var/log/messages, journalctl, etc. Thanks.
