[ovirt-users] oVirt/RHV 4.3.6: How to boot a Q35/UEFI VM from CD?

Hi I've been experimenting with UEFI on RHV 4.3.6 using Windows Server 2019 but I guess posting on the oVirt list might reach a wider audience. I've used UEFI guests on other KVM-based virtualizations, but I have been unable to detect a UEFI-bootable CD using Q35 VMs with or without SecureBoot in RHV 4.3.6 since it doesn't even propose to load the UEFI loader from within OVMF. It seems to show the CD-ROM drive, but I cannot boot from file the disc from OVMF: Are there any hints? (I've tried finding something more detailed in the Docs though) I'd like investigate UEFI and SecureBoot on oVirt/RHV even if it's still considered a tech preview. (I've been using KVM-based UEFI VM for years already on other platforms and distributions with no particular issues, rather advantages overall). Regards Mathieu
