Right > But that needs to be set to my own authority ca file. Right, but you should not modify this file, it is owned by engine and your changes will be lost on the next upgrade. As documented in the top of the file, you need to create a drop in file: $ cat /etc/ovirt-imageio/cond.d/99-local.conf [tls] ca_file = ... I think you need to change the key_file and cert_file, otherwise clients connected to imageio server may fail to verify the server certificate.

This works but you will lose the change on the next update, and as you know modifying python code in production is risky.
