Communication from Engine to ovirt-provider-ovn via OpenStack API looks
good. The problem seems to be in the communication from
ovirt-provider-ovn to engine's sso.
The hostname to resolve seems to be 'engine-host'.
Hi all, so it seems that updating from 4.2.7 to 4.2.8 wiped the file
entirely...
In fact now I only have:
[root@ovmgr1 ~]# ll /etc/ovirt-provider-ovn/conf.d/
total 4
-rw-r--r--. 1 root root 194 Jan 14 16:18 README
[root@ovmgr1 ~]#
While on another similar environment in 4.2.7 I still have:
[root@ovirt ~]# ll /etc/ovirt-provider-ovn/conf.d/
total 8
-rw-r--r--. 1 root root 561 Dec 31 2017 10-setup-ovirt-provider-ovn.conf
-rw-r--r--. 1 root root 194 Oct 17 05:56 README
[root@ovirt ~]#
So in my updated environment I think it tries to use the default file
values in /etc/ovirt-provider-ovn/ovirt-provider-ovn.conf
[OVIRT]
ovirt-host=https://engine-host
The question now is why it has been wiped out?
This environment has external VM working as ovirt engine, so not SHE.
I see that engine-backup doesn't run backup of the /etc/ovirt-provider-ovn/
... could it be useful to include it?
I should have a VSPhere image backup of the VM so I should be able to
restore the file. I'll see...
In the mean time could it be the update of the package has been the
responsible?
Eg, in my 4.2.7 env I currently have ovirt-provider-ovn-1.2.16-1.el7.noarch
The update to 4.2.8 in the other system has put
in ovirt-provider-ovn-1.2.18-1.el7.noarch
HIH debugging
