Is this specifically talking about VFs that are assigned to a guest via PCI Passthrough (<hostdev>)? Or is using macvtap in passthrough mode (with the guest using virtio) acceptable?
For the former case (PCI passthrough), as a possible solution to Bug 691539, I sent a proposal upstream a couple weeks ago that, while incomplete/incorrect, should lead to something that will fulfill the requirements:
For the latter case (macvtap in passthrough mode), this is already committed upstream as of libvirt-0.9.4, and thus will be in RHEL6.2 (of course there could be bugs and/or missing details). See http://www.libvirt.org/formatnetwork.html, in particular the "passthrough" forward mode for more info.
jjarvis - you've reset the needinfo I set for the question at the beginning of Comment 2, but didn't answer the question.
Sorry, I was only setting priority, milestone, etc., not answering the question.
Setting back to NEEDINFO of IBM.

I did some initial verification with RHEL 6.2 and this request is covered there. I think, the feature request can be dropped and if - after additional verification - additional issues show up they could be handled as bugs.
