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-without-cluster/ Might I ask what you goal is?

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 postgresql 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.
