What we would rather do in KVM, is have the VFs appear in the host as
standard network devices. We would then like to back our existing PV
driver to this VF directly bypassing the host networking stack. A key
feature here is being able to fill the VF's receive queue with guest
memory instead of host kernel memory so that you can get zero-copy
receive traffic. This will perform just as well as doing passthrough
(at least) and avoid all that ugliness of dealing with SR-IOV in the guest.
This argues for ignoring the SR-IOV mess completely.
It does, but VF-in-host is not the only model that we want to support.
It's just the most appealing.
There will definitely be people who want to run VF-in-guest.
