You cannot have bridges with the same address without causing some
serious network problems.
You can simply set the second bridge to another address using:
# ip link set dev xenbr1 address FE:FF:FF:FF:FF:FE
 after it is created, but before it enslaves the interfaces.

Alternatively, use MAC addresses from the 10:00:00:x:x:x range, which
are reserved for private use (and do not set the low bit of the first
octet, or you will create a multicast MAC address).
