Thanks to all for some great advice.
I'll use this in my argument to properly provision. The VM Admins are a stingy
group.

Good point Rick about not configuring your instance yet, especially if you want
to be able to connect the instances because if you clone those VM's your unique
id will be the same and it won't work.
I install the software on VM's, have all the mountpoints ready etc but be sure
not to clone with the instance configured, that will hurt if you ever want to
connect the server to server.
And like you said, they do take up a lot of resources and I think you should
not use the normal storage subsystem since that is what you are protecting but
taking these things into account it works really well.
