To make it more clear; the hardware SRIOV device is different that normal:
<cpaelzer> TL;DR this special device has VFs that have NO PF associated
<cpaelzer> software doesn't understand this
Though per comment #3; it seems odd that a Xenial/Queens with the same kernel (HWE) works OK. So some tracing in libvirt/nova to confirm different paths, I think.
