That makes no sense - there is (normally) only one MAC address for a 
physical interface - and it will be the same for IPv4, IPv6, 
AppleTalk, DECnet, ... So whatever you do with the interface, all 
protocols will use the same MAC address - the cases where multiple 
MAC addresses are used are fairly uncommon and don't apply in your 
situation. A fixed address isn't essential, but it can make a few 
things a lot easier - DHCP being just one of them.
But to answer your question, it doesn't really matter what guest OS 
you use, or what your hosting setup is - in general you would use the 
OS specific tools to configure your guest networking. You may be 
provided with a DHCP service (or other configuration service for 
IPv6) but that's not really related to Xen or virtualisation in 
general.
In Debian (and it's derivatives) you'd edit /etc/network/interfaces 
and add an "iface <name> inet6 ..." entry, plus configure an IPv6 
firewall, configure IPv6 services if needed*, and so on.
* Many services will "just work" when you enable IPv6. I know Postfix 
has been happy for some time.
