SR-IOV should work (or general PCI passthrough), it’s then transparent to oVirt. Did you not succeed with setting up SR-IOV or generic passthrough of the HCA?

Well, at least for generic passthrough the PCI device would be detached from the host so should not be recognized/touched by oVirt networking code at all.
