Makes sense for the host side to have naming convention tied
to the guest. Example as a prefix: guest0-eth0. Would it not
be interesting to have the host also manage these interfaces
via standard tools like ip or ifconfig etc? i.e if i admin up
guest0-eth0, then the user in guest0 will see its eth0 going
up.
    

Please no.

Now I am open to radically different designs if they allow the
implementation cost to be lower and they have clean semantics,
and don't wind up being an ugly unmaintainable wart on the linux
networking stack.  The only route I could imagine such a thing coming
from is something like tagging flows, in some netfiler like way.
Which might allow ifconfig guest-eth0 from the host without problems.
But I have not seen such a design.
  

Right.  New tools to support new features would probably be tidier, anyway.
