Does this help?

MAC addresses

Virtualised network interfaces in domains are given Ethernet MAC 
addresses. By default xend will select a random address, this will differ 
between instantiations of the domain. If it is required to have a fixed 
MAC address for a domain (e.g. for using with DHCP) then this can be 
configured using the mac= option to the vif configuration directive (e.g. 
vif = ['mac=aa:00:00:00:00:11']).
