These are mostly not really Xen questions, more a general networking issue.

The first question is, how does the hoster present your networking ? And how is 
your Xen networking set up ?

If (for example) your hoster presents you an ethernet cable, with your own IP 
range and a gateway address for their router; and you are using bridging on 
Xen; then it will simply be a case of configuring an IPv6 address on each box.
Configuring IPv6 can be done several ways, and that depends on how the routers 
are configured. At it's simplest, the router(s) will advertise themselves and 
your devices can self-assign an address - auto configuration which should "just 
work". For hosting, you probably want to manually configure IPv6 addresses so 
they are fixed.
