Today packets are written/read from/to Qemu to/from tun device, how 
would the use case with vhost will look like?

Is this the user setting an uplink NIC + bridge + per VM tun device but 
the packets will go from/to virtio-net in the guest kernel to/from vhost 
in the host kernel and then from/to vhost to/from tun? so eventually no 
packets will be seen by the qemu process? I don't see what these scheme 
buys people, I got very much confused.

Or.
