Thank you @Patrick42 , I do get the same behavior on legacy hardware. I am under constraints, as it is in an airgapped environment where my only installation media is the basic cdrom/dvd. And I need to create the vm’s in that airgapped environment. I was just wondering if there is any way I can make sure to either fail (hard) the installation if the architecture isn’t supported by the OS or installation media, instead of this silent endless loop waiting for the correct installation media to magically appear. I can install by hand with a console, but having to do this more than 20 times will be a difficult task to mainstream. Hence the urge to install with kickstart from a media under my control.
