(Get the code!)
For the time being I only found a system with a full device to passthrough not a VF.
That worked fine for me, the guest gets the dev and can load its drivers.
[ 297.340525] mlx5_core 0000:00:08.0: Port module event: module 0, Cable unplugged
[ 297.361111] mlx5_core 0000:00:08.0: MLX5E: StrdRq(0) RqSz(1024) StrdSz(256) RxCqeCmprss(0)
[ 297.572313] mlx5_core 0000:00:08.0 ens8: renamed from eth0
But since that was "only" PCI-passthrough and not yet VFs I'm looking forward to your answers on your case.
Once more thing you could track and report is the guests "dmesg -w" while trying to attach to see if there is anything appearing there or aborting much earlier.
