[ovirt-users] Booting VMs from RHEL ISOs fail

Ever since I deployed oVirt a couple months ago, I've been unable to boot any VMs from a RHEL ISO. Ubuntu works fine, as does CentOS. I've tried multiple RHEL 8 ISOs on multiple VMs.  I've destroyed and re-uploaded the ISOs, and I've also destroyed and re-created the VMs. Every time I try to boot a VM to a RHEL 8 ISO, the console just tells me that "No boot device" was found. Can anyone think of any reason why other ISOs would work, when RHEL ISOs do not work? How can I troubleshoot this further? I really need to get a server up and running with Podman.  Sent with ProtonMail Secure Email.
