If you really need to completely get rid of the old name in wherever it appears, it's best to start from scratch, and perhaps then import your storage domains if needed. In principle, you might manually recreate all the pki on an existing setup, as you asked. This is a delicate process, and I am not aware of a documented and tested procedure to do this. See also: https://www.ovirt.org/develop/networking/changing-engine-hostname.html Also, please note that 4.5.0 was released and 4.4 is no longer supported - please upgrade. But my answer remains the same for 4.5 regardless. Best regards, -- Didi
