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.
I think that's a pretty bad idea. If the host OS goes down then so
does all the guests. Not to mention the latency requirements of OD
servers. Really you would want your replica on a separate switch or
network.
