That's right, these need to be MAC addresses for the virtual device
itself, which must be unique on your network segment.

You can either use address from an OUI which you control (unlikely in
most cases), from the Xen OUI (00:16:3e:xx:xx:xx) or any address with
the locally administered bit set. Most people just pick a random address
from either of the last two.

I wrote a CGI script to generate correctly formed randomized MAC
addresses:
