Any reason for that, considering that RHEL 8 is not listed among the supported ones (for hypervisor or engine) neither in latest stable 4.3.3 ( https://ovirt.org/release/4.3.3/#centos--rhel ), nor in latest release candidate for upcoming 4.3.4 ( https://ovirt.org/release/4.3.4/ )?

Supported only as a guest, both on oVirt 4.3.3 (even if here the term "support" could be less appropriate perhaps...) and in RHV 4.3 ( https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/virtual_machine_management_guide/installing_guest_agents_and_drivers_linux )
