Good to see this discussion going. I share the same feeling that the
decision of plugging the primary (passthrough) should only be made
until guest driver acknowledges DRIVER_OK and _F_STANDBY.
Architecturally this intelligence should be baken to QEMU itself
rather than moving up to management stac

Sure. This is not sufficient for a complete solution, but is Qemu the right
place
to manage primary/standby interfaces?
I think the other steps including plugging/unplugging the primary interface
needs
to hand

I don't think this is sufficient.
