Otehr infos:
1) time is ok between 3 hosts
2) hosted-engine --vm-status gives this
[root at ovirt01 ~]# hosted-engine --vm-status
--== Host 1 status ==--
Status up-to-date : True
Hostname : ovirt01.localdomain.local
Host ID : 1
Engine status : {"health": "good", "vm": "up",
"detail": "up"}
Score : 3400
stopped : False
Local maintenance : False
crc32 : a12c7427
Host timestamp : 397487
Extra metadata (valid at timestamp):
metadata_parse_version=1
metadata_feature_version=1
timestamp=397487 (Sun Nov 20 14:59:38 2016)
host-id=1
score=3400
maintenance=False
state=EngineUp
stopped=False
[root at ovirt01 ~]#
[root at ovirt02 ~]# hosted-engine --vm-status
You must run deploy first
[root at ovirt02 ~]#
[root at ovirt03 ~]# hosted-engine --vm-status
You must run deploy first
[root at ovirt03 ~]#
So it seems there is something wrong with the setup.
I thought that deploying from web admin gui would have put the hosts into
the same environment.....
