I use the following snippet in my domU setup script to create a MAC address
for a new host:
MACADDR="aa:00:$(echo $VHOSTNAME | md5sum \
 | sed 's/^\(..\)\(..\)\(..\)\(..\).*$/1円:2円:3円:4円/')"
Then substitute MACADDR into the template config file we use here.
Yes, there is a (small but) non-zero chance of collision. No, I don't care.
