I actually think this is a poor idea. Part of the idea of directory
replicas (be they AD or OD) is that they are on physical machines in
different locations. This puts the login machines closer to the
clients that are actually using them. In fact, AD has the concept of
"sites" that allows the client to automatically prefer domain
controllers on the same subnet. Also, virtualizing a service does not
save you from a hardware problem. What happens if your box running an
OD master and 3 ODRs eats it? You have no OD replicas to take over?
Isn't that the point of a replica to begin with?

What would be a real world use for having this?
Just curious.
If you have multiple physical servers that are lightly loaded, you
can run
them all on the same hardware. For example, many Active Directory
shops run
their Directory Controllers virtualized, because those don't really
do a lot
that needs wicked-fast hardware for their own exclusive use.
This is the exact example I heard at a server seminar this week -
host an Open Directory Replica in a VM on the same hardware as your
Open Directory Master. I would probably host it on another machine,
but still, it got me thinking.
...got me thinking I have some learning to do about
virtualization. :)
