Bind the backend virtio device to the vf I can see this making sense as a feature bit that says VFs are not initialized by default and must first be setup through an admin command. This will likely need to be a feature bit because it's changing behaviour outside of admin commands. Then, we can have: ADMIN_SETUP VF# ADMIN_CLEANUP VF# I like this because this generalizes CREATE/DESTROY that SIOV guys proposed. Why do we need an id as a level of indirection though? What is wrong with just using VF# directly? -- MST
