I have tested all options but oVirt seems to tick most required boxes.

OpenStack : Too complex for use case
Proxmox : Love Ceph support but very basic clustering support

Not sure if you know that rbd-nbd support is going to be implemented to Cinderlib. I could understand why oVirt wants to support CinderLib and deprecate Cinder support.
Yes, we love oVirt for “that should work like this”, before oVirt 4.4...
Now imagine: you current cluster runned with qemu-rbd and Cinder, now you upgrade oVirt and can’t do anything - can’t migrate, your images in another oVirt pool, engine-setup can’t migrate current images to MBS - all in “feature preview”, older integration broken, then abandoned.
