Help me to understand this please.

On a xen-host there is for example the following interfaces:

xenbr0 xenbr1  - which I understand as Xen bridge interfaces.
peth0  peth1
vif0.0, vif0.1, vif1.0, vif1.1


So which of those do I configure in Racktables for the host?

On the guest I have eth0 and eth1 as IPv4 configured.  Then, according
to what you said above I must use one veth-port on the guest.  So I
define such a port.  Does it matter what I call it?  

How do I link it with the interface on the host?

What if another host has exactly the same interfaces as this one?
