I always thought the "frontend" was the device the guest
saw (the 16650 UART or whatever). invocation.html has bits
talking about "virtio hvc console frontend device" which
seem like they also use that terminology.
If we want to clean up the naming it might be helpful to have
a comment somewhere documenting the different components and
what names we give them and how they fit together (or even
better, something in docs/devel/...)
thanks
