This should be : scl enable rh-postgresql95 bash
psql: FATAL: Peer authentication failed for user "postgres"
I am not sure why it is trying to execute the command while enabling.

Hi,
that sure looks like postgresql SCL packages. Software collections are installed into /opt and need to be enabled using the `scl enable <collection name>` command to allow their usage.

But I actually installed it manually, still no succeed. But ovirt engine is working.

If the engine user is not accessible directly, why then in this
command
you use it?:
psql -U engine engine -c "UPDATE vdc_options set option_value = 'false' WHERE option_name = 'SSLEnabled';"
I am not really good in managing databases, I also didn't have
installed after finishing oVirt engine installation and even managing to deploy everything. Does it mean that no database was created at all? I have chosen automatic and local creation in all fields related to database while installing oVirt engine.
Can you paste the output of the following command
rpm -qa |grep postgres

Hi,
I think what you are looking for is mostly this: https://github.com/oVirt/vdsm/blob/master/lib/vdsm/api/vdsm-api.yml
The best way to see what the traffic is is to disable SSL. The postgres database is installed and accessible using the postgres user (the engine user is not allowed to access it directly).
You might also be interested in the vdsm fake project we use as node simulator. Its readme will tell you exactly how to do this: https://github.com/oVirt/ovirt-vdsmfake
I wrote an article some time ago that explained how to setup a development environment without real hosts:
https://www.ovirt.org/blog/2016/11/testing-ovirt-changes-wit
hout-cluster/
Might I ask what you goal is?
Best regards
