    I use this to make MACs for my VMs and virtual NICs. The 00:16:3E prefix means it’s Xen virtualization, so change this part as needed.

    #!/usr/bin/python
    
    # macgen.py script to generate a MAC address for guests on Xen
    
    import random
    
    def randomMAC():
    	mac = [ 0x00, 0x16, 0x3e,
    		random.randint(0x00, 0x7f),
    		random.randint(0x00, 0xff),
    		random.randint(0x00, 0xff) ]
    	return ':'.join(map(lambda x: "%02x" % x, mac))
    
    print (randomMAC())
    

    Use

    $ macgen.py 
    00:16:3e:17:ed:b1
