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 Gianluca
