    mac = [ 0xaa, 0x00, 0x00,
            random.randint(0x00, 0x7f),
            random.randint(0x00, 0xff),
            random.randint(0x00, 0xff) ]
    return ':'.join(map(lambda x: "%02x" % x, mac))

You could try adding the following ahead of the above code in
tools/python/xen/xm/create.py:

random.seed(time.time())

(you may need to add an 'import time' at the top of the file).
